Fig. 2 is a schematic flow chart of an IP address updating method provided in the related art, and as shown in fig. 2, the IP address updating method includes:
s201, a terminal sends a domain name resolution request to a domain name resolution server; the domain name resolution request comprises a target domain name; the server receives a domain name resolution request sent by the terminal.
S203, the domain name resolution server responds to the domain name resolution request, and determines a target IP address list corresponding to a target domain name based on the target domain name in the domain name resolution request.
S205, the domain name resolution server sends a target IP address list to the terminal, and the terminal receives the target IP address list.
S207, the terminal starts a timer and determines that the timer is overtime.
The running time of the timer may be preset by the terminal itself or configured by the domain name resolution server, and the running time of the timer may be 1 day, 7 days, 14 days, or the like.
And S209, updating the target IP address list in the domain name resolution server in the running process of the timer of the terminal.
S211, the terminal sends a domain name resolution request to the server again; a server receives a domain name resolution request sent by a terminal; the domain name resolution request includes a target domain name.
In S211, the terminal transmits the domain name resolution request again at the timing when the timer expires.
S213, the domain name resolution server responds to the domain name resolution request, and determines an updated target IP address list corresponding to the target domain name based on the target domain name in the domain name resolution request.
S215, the domain name resolution server sends the updated target IP address list to the terminal, and the terminal receives the updated target IP address list.
In the related art, if the terminal updates the target IP address list in the domain name resolution server during the running period of the timer, but the target IP address list in the terminal is not updated yet, so that the terminal still accesses through the target IP address list, which results in a high failure rate of the terminal.
Fig. 3 is a schematic view of an implementation flow of a method for updating an IP address provided in an embodiment of the present application, as shown in fig. 3, where the method is applied to a terminal, and the method includes:
s301, the terminal sends a first access request to the gateway.
The first access request may be used to request a first access result corresponding to the first access request, where the first access result includes a resource that the terminal needs to access.
The terminal may store mappings between a plurality of domain names and IP address lists, for example, the terminal may store domain name a, domain name B, domain name C, and the like, and store mappings between domain name a and a first IP address list, mappings between domain name B and a second IP address list, and mappings between domain name C and a third IP address list. Each IP address list may include at least one IP address.
When the terminal needs to access the domain name B, the terminal may first query whether the domain name B exists inside, and after the query, access is performed through the IP address in the second IP address list. However, when the terminal needs to access the domain name G, the terminal queries the domain name stored in the terminal and does not find the domain name G, at this time, the terminal may send a domain name resolution request including the domain name G to the domain name resolution server, and after receiving the domain name resolution request, the domain name resolution server sends an IP address list corresponding to the domain name G to the terminal, so that the terminal may access through the IP address list corresponding to the domain name G. Further, the terminal may store the domain name G and the IP address list corresponding to the domain name G into an internal storage (e.g., SDK), so that when the domain name G is accessed next time, the IP address list corresponding to the domain name G may be obtained by querying the internal storage.
In this embodiment, the terminal may determine an IP address of a first server to be accessed, and send a first access request to the gateway based on the IP address of the first server. For example, before S301, the terminal may perform obtaining a first IP address list from the internal storage, and determine an IP address of the first server from the first IP address list, and then perform access using the IP address of the first server, that is, send an access request to the gateway, so that the gateway forwards the first access request to the first server, thereby establishing a connection between the terminal and the first server. It can be appreciated that the IP address of the first server can be included in the first list of IP addresses. The first IP address list may be stored in a Software Development Kit (SDK) of the terminal.
S303, the terminal receives the notification message and the first access result sent by the gateway; the notification message is used to indicate that the first IP address list is updated.
After the gateway receives the first access request, the gateway may forward the first access request to the first server, and receive a first access result fed back by the first server after responding to the first access request.
In the embodiment of the application, the notification message is used for the terminal to acquire the second IP address list obtained after the first IP address list is updated from the domain name resolution server.
In one embodiment, the gateway may integrate the access result and the notification message in one signaling message and transmit the signaling message to the terminal. In another embodiment, the gateway may send the access result and the notification message separately through two signaling messages.
The first IP address list may be an IP address list corresponding to the gateway, for example, the IP address list corresponding to the gateway may be one IP address list or a plurality of IP address lists, and the first IP address list may be one IP address list of the plurality of IP address lists corresponding to the gateway.
In one embodiment, the IP address of the first server may be included in the first IP address list, so that the terminal may determine the first IP address list through the IP address of the first server after receiving the notification message.
In another embodiment, the IP address of the first server may not be included in the first IP address list, but the notification message may include a first domain name, so that the terminal may determine the first IP address list according to the first domain name after receiving the notification message.
S305, the terminal obtains a domain name resolution result from the domain name resolution server based on the notification message; and the domain name resolution result comprises a second IP address list obtained after the first IP address list is updated.
And the domain name resolution result at least comprises a second IP address list. The IP address of the first server may or may not be included in the second list of IP addresses.
In the embodiment of the application, after the terminal receives the notification message, the terminal determines that the first IP address list is updated, and then obtains the second IP address list obtained after the first IP address list is updated from the domain name resolution server, so that the terminal can obtain the second IP address list in time, and further the access success rate of the terminal can be improved.
Fig. 4 is a schematic flow chart illustrating an implementation of another IP address updating method provided in the embodiment of the present application, and as shown in fig. 4, the method includes:
s401, the domain name resolution server sends a notification message to a gateway; and the gateway receives the notification message sent by the domain name resolution server.
The notification message is used for indicating that the first IP address list is updated, and the terminal acquires a second IP address list obtained after the first IP address list is updated from the domain name resolution server.
In one embodiment, the notification message may not include the first domain name corresponding to the first IP address list, and the terminal may determine the first domain name corresponding to the first IP address list by using the IP address of the first server. For example, since the terminal internally stores a mapping between the first domain name and the first IP address list, the terminal may determine the first domain name corresponding to the first IP address list based on the IP address of the first server and the mapping. In another embodiment, the notification message may include the first domain name, so that the terminal may resolve the notification message to obtain the first domain name.
In one embodiment, the domain name resolution server may generate a notification message upon determining that an update has occurred to the first list of IP addresses, and send the notification message to the gateway. The first IP address list update may be: and adding the IP address to the first IP address list, reducing the IP address in the first IP address list or changing the IP address in the first IP address list.
In an example process, the first IP address list may include M IP addresses, each of the M IP addresses corresponds to one service server, and the domain name resolution server may receive a change message of an IP address in the first IP address list, which is sent by any one of the M service servers in one-to-one correspondence with the M IP addresses through the gateway, so that the domain name resolution server updates the first IP address list based on the change message. Wherein M is an integer greater than or equal to 1. In another implementation, the domain name resolution server may receive a change message of the IP address sent by the other device, and update the first IP address list based on the change message.
In another example process, the second IP address list may include N IP addresses, and each of the N IP addresses corresponds to one service server. Wherein N is an integer greater than or equal to 1.
S403, the terminal sends a first access request to the gateway; the gateway receives a first access request sent by the terminal.
The embodiment of the application does not limit the sequence of the notification message and the first access request received by the gateway.
S405, the gateway sends a notification message and a first access result to the terminal; and the terminal receives the notification message and the first access result sent by the gateway.
It should be understood that the gateway sends the notification message and the first access result to the terminal after receiving the notification message and receiving the first access request sent by the terminal. The first access result corresponds to the first access request.
S407, the terminal obtains a domain name resolution result from the domain name resolution server based on the notification message; the domain name resolution result comprises a second IP address list obtained after the first IP address list is updated.
In the embodiment of the application, through an interactive process among the terminal, the gateway and the domain name resolution server, the domain name resolution server sends the notification message to the gateway when determining that the first IP address list is updated, so that the terminal receives the notification message through the gateway and acquires the second IP address list obtained after updating the first IP address list based on the notification message, and further, after the first IP address in the domain name resolution server is updated, the terminal can also obtain the updated second IP address list in time, and thus, the access success rate of the terminal can be improved.
Fig. 5 is a schematic flow chart illustrating an implementation of another IP address updating method provided in the embodiment of the present application, and as shown in fig. 5, the method includes:
s501, the domain name resolution server sends a notification message to the gateway.
The notification message is used for indicating that the first IP address list is updated, and for acquiring a second IP address list obtained after the first IP address list is updated from the domain name resolution server after the terminal receives the notification message sent by the gateway.
S503, the terminal determines the IP address of the first server from the first IP address list.
The communication Protocol between the terminal and the Gateway may be a Gateway to Gateway Protocol (GGP) or other network protocols.
The SDK of the terminal may store a mapping between each of the plurality of domain names and each of the IP address lists. The terminal may determine the first domain name to be accessed based on an operation of the terminal by a user, so as to determine a first IP address list corresponding to the first domain name in the plurality of mappings. For example, in the case where the first domain name is www.baidu.com, the terminal may determine the list of IP addresses corresponding to domain name www.baidu.com among the plurality of maps stored in the SDK, so that access can be made based on one IP address in the obtained list of IP addresses corresponding to www.baidu.com.
In an embodiment of the application, in the first IP address list, the first IP address list may include not only at least one IP address but also at least one weight parameter in one-to-one correspondence with the at least one IP address, and the terminal may determine the first-visited IP address based on the at least one weight parameter, and if access fails based on the first-visited IP address, determine the second-visited IP address based on the at least one weight parameter until access succeeds. The terminal may randomly select one of the at least one IP address as the connection based on a weighted random algorithm or a random weighted algorithm.
S505, the terminal may send a first access request to the gateway based on the IP address of the first server. The gateway receives a first access request sent by the terminal.
The first IP address list may include: m IP addresses and M weight parameters corresponding to the M IP addresses one by one, wherein M is an integer greater than or equal to 1; the terminal may determine an IP address of the first server from the M IP addresses based on the M weight parameters, and may further send a first access request to the gateway based on the IP address of the first server.
After the gateway receives the first access request, the service server accessed by the terminal can be determined to be the first server based on the IP address of the first server in the first access request. The gateway may then forward the first access request to the first server, and the first server, upon receiving the first access request, responds to the first access request and determines a first access result based on the first access request, and then sends the first access result to the gateway.
S507, the gateway sends a notification message and a first access result to the terminal; and the terminal receives the notification message and the first access result sent by the gateway.
S509, the terminal determines the first domain name corresponding to the first IP address list based on the notification message.
The terminal may trigger a process of determining a domain name corresponding to the IP address of the first server after receiving the notification message. In one embodiment, the terminal may determine the first domain name corresponding to the IP address of the first server based on a mapping between the first domain name and a first IP address list stored in the terminal.
S511, the terminal sends a domain name resolution request to a domain name resolution server; the domain name resolution request comprises a first domain name; and the domain name resolution server receives a domain name resolution request sent by the terminal.
The communication protocol between the terminal and the domain name resolution server is HTTP. HTTP is the most widely used network transport protocol on the internet, and all WWW documents comply with this standard. With the rapid development of internet technology, network services become an indispensable service in people's life, and currently, internet enterprises generally use domain names to provide services for users.
S513, the domain name resolution server sends a domain name resolution result to the terminal; and the terminal receives a domain name resolution result sent by the domain name resolution server.
And the domain name resolution result comprises a second IP address list obtained after the first IP address list is updated.
The DNS data (e.g., the second IP address list) sent by the domain name resolution server to the terminal is easily falsified and forged by a third party if it is not verified. In order to solve the problem, when the domain name resolution server sends the second IP address list to the terminal, the second IP address list may be encrypted by an asymmetric encryption method, where the encryption method may be that the domain name resolution server encrypts the second IP address list by using a private key, and the terminal decrypts the encrypted data by using a public key, or the encryption method may be that the domain name resolution server encrypts the second IP address list by using a public key, and the terminal decrypts the encrypted data by using a private key.
When the domain name resolution server is encrypted by the private key, the domain name resolution server may perform hash calculation on the second IP address list to obtain a first hash value; then, the first hash value can be encrypted by adopting a private key to obtain a first signature; the domain name resolution result may then be determined based on the first signature and the second list of IP addresses, e.g., by encoding the first signature and the second list of IP addresses. The domain name resolution result may include the first signature and the second IP address list.
And S515, the terminal checks the domain name resolution result, and updates the first mapping stored in the terminal into the second mapping after the checking is successful.
Wherein the first mapping may include: a mapping between the domain name and the first list of IP addresses, the second mapping may comprise: a mapping between the domain name and the second list of IP addresses.
The first mapping and the second mapping may both be stored in domain name resolution information or a domain name resolution module of the SDK.
When the terminal decrypts with the public key, the terminal can first determine the public key corresponding to the domain name resolution server; then, the public key can be adopted to decrypt the first signature to obtain a first hash value; then, the hash value of the second IP address list can be calculated to obtain a second hash value; and if the first hash value is the same as the second hash value, determining that the verification of the domain name resolution result is successful.
In one embodiment, the public key corresponding to the domain name resolution server may be stored inside the terminal, from which the terminal may obtain the public key corresponding to the domain name resolution server. In one implementation scenario, the public key may be extracted from a digital certificate stored internally in the terminal. In another embodiment, the public key corresponding to the domain name resolution server may be sent by the domain name resolution server to the terminal, the public key may be included in the domain name resolution result, or the domain name resolution server sends the public key to the terminal separately. In still another embodiment, the domain name resolution server may further send a digital certificate to the server, where the digital certificate may include the public key, so that the terminal may obtain the public key through the digital certificate, where the digital certificate may be included in the domain name resolution result, or the domain name resolution server separately sends the digital certificate to the terminal.
After S515, the terminal may perform access to the first domain name based on the second IP address list.
If the second IP address list includes one IP address, the IP address is the IP address of the first server, and the terminal can access the first IP address in the IP address list. If the second IP address list comprises at least two IP addresses, the terminal can determine a first weight parameter based on the at least two weight parameters; and then determining a first IP address to be accessed corresponding to the first weight parameter from the at least two IP addresses, and accessing by adopting the first IP address to be accessed.
In one embodiment, in the case that the terminal fails to access by using the first IP address to be accessed, the terminal may determine a second weight parameter other than the first weight parameter from the at least two weight parameters; and then, a second to-be-accessed IP address corresponding to the second weight parameter can be determined from the at least two IP addresses, and the second to-be-accessed IP address is adopted for accessing.
In this way, since the terminal modifies the first IP address list stored therein into the second IP address list, the terminal can access through the second IP address list when determining the access request for the domain name next time.
After the terminal updates the first IP address list into the second IP address list, if the gateway in the second IP address list is not notified, the gateway does not know whether the terminal updates the first IP address list. To solve this problem, the method for updating an IP address may further include performing the steps of: the terminal sends an update completion message to the gateway; the gateway receives an update completion message sent by the terminal; the update completion message is used to instruct the terminal to complete updating the stored first IP address list.
The terminal may send the update completion message to the gateway at a time when the terminal receives the domain name resolution result sent by the domain name resolution server, or after the terminal updates the internally stored first mapping to the second mapping.
After receiving the update completion message, the gateway may send a second access result to the terminal after receiving a second access request sent by the terminal based on the IP address of the second server based on the update completion message. After that, the gateway receives the notification message sent by the domain name resolution server again, and after receiving the access request of the terminal, sends the notification message to the terminal.
In the embodiment of the application, through an interactive process among the terminal, the gateway and the domain name resolution server, the second IP address list may include at least one IP address and at least one weight parameter corresponding to the at least one IP address one to one, so that the terminal can determine an IP address to be accessed first from the second IP address list by using a weight random algorithm, thereby avoiding a situation that the gateway corresponding to the first IP address generates request aggregation because the terminal starts to access from the first IP address in each access in the related art. In addition, the terminal verifies the second IP address list sent by the domain name resolution server, so that the second IP address is prevented from being falsified and forged by a third party.
Fig. 6 is a schematic flow chart of obtaining a second IP address list by a terminal according to an embodiment of the present application, and as shown in fig. 6, a manner of obtaining the second IP address list by the terminal may be implemented by the following steps S601 to S611:
s601, the terminal sends a DNS request to a domain name resolution server.
The DNS request may include a domain name, for example, the domain name may be www.domain.com, and the DNS request may be a domain name resolution request in the above embodiment.
S603, after receiving the DNS request, the http DNS server queries a second IP address list corresponding to the domain name in the DNS request.
As shown in fig. 6, the second IP address list has three IP addresses, which are weighted (corresponding to the weighting parameters of the above embodiment) 0.4, 0.3 and 0.3 respectively, compared to IP1, IP2 and IP 3.
S605, the http dns server may encrypt the second IP address list with a private key.
The encryption mode is that the HTTPDNS server calculates the hash value of the second IP address list to obtain a first hash value, and encrypts the first hash value to obtain a first signature.
S607, the http DNS server may return the result of the DNS request to the terminal.
The returned result may be a domain name resolution result, which includes the first signature and the second IP address list.
And S609, the terminal adopts the public key to decrypt and verify.
The decryption and verification method comprises the following steps: determining a public key corresponding to a domain name resolution server; decrypting the first signature by using a public key to obtain a first hash value; calculating the hash value of the updated IP address list to obtain a second hash value; and if the first hash value is the same as the second hash value, determining that the verification of the domain name resolution result is successful.
The http dns server may issue the public key, or the http dns server may issue a certificate, so that the terminal obtains the public key through the certificate.
S611, the terminal updates the first IP address list into a second IP address list.
After the verification is successful, the terminal may determine that the second IP address list is sent by the domain name resolution server, and then the terminal may update the first IP address list to the second IP address list. The updating process of the terminal may be deleting the first IP address list and writing the second IP address list.
In the embodiment of the application, the request return result is subjected to asymmetric encryption, so that the safety of data content in the network transmission process is effectively ensured, and the content cannot be tampered; meanwhile, by issuing a certificate and a decryption Token (Token) (which can be understood as a public key) to a legally authorized terminal, an irrelevant party or a malicious user is prevented from using the service. The direct Token issuing mode also avoids performance loss caused by connecting multiple handshakes by using Transport Layer Security (TLS).

S703, the terminal sends an access request to the gateway.
The terminal may send an access request to the gateway based on the address AAA.
S705, the gateway forwards the request to the service server a.
The service server a corresponds to the address AAA.
S707, the HTTPDNS server determines that the IP address list AAA is changed into the IP address list BBB, and sends a notification message to the gateway.
The IP address list BBB includes an IP address BBB. The notification message is used to indicate that the IP address list AAA has changed.
S709, the gateway sends the access result and the notification message to the terminal.
The notification message is used for notifying the terminal IP address list AAA change.
S711, after obtaining the IP address list BBB based on the notification message, the terminal may update the internally stored IP address list AAA to the IP address list BBB.
After that, the terminal can access the service server B based on the address BBB in the IP address list BBB.
In the embodiment of the application, when the IP address configuration is changed, the gateway protocol is used for informing the user that the IP address is modified. After receiving the message sent by the gateway, the user (terminal) sends Dns request to refresh the IP address of the corresponding domain name in real time, thereby achieving the capability of real-time refreshing.
In the embodiment of the application, based on the HTTPDNS service, a set of technical scheme with weight, which can refresh IP addresses in real time and prevent hijacking is provided, so that the problems of request aggregation, content tampering, terminal caching and the like in the conventional HTTPDNS are solved, and the safety, availability and flexibility of the HTTPDNS are greatly improved.
In the embodiment of the application, the HTTPDNS service returns the weighted IP addresses, thereby ensuring the balance of IP address access; the method adopts asymmetric encryption to carry out encryption transmission on HTTPDNS communication data, thereby ensuring that the content is prevented from being tampered; and the gateway protocol informs the user of refreshing the cache in real time, so that the real-time property is improved.
