Description

Client IP address allocation method and device
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for allocating a client IP address.
Background
DHCP (Dynamic Host Configuration Protocol) is used to dynamically allocate network Configuration parameters such as an IP address to a network device. The client requests the DHCP server to distribute configuration information such as IP address, and the DHCP server returns the configuration information such as IP address distributed for the client to realize the configuration of the configuration information such as IP address.
When the DHCP server and the client are in the same network segment, the DHCP server can directly allocate the IP address for the client sending the IP address allocation request. When the DHCP server and the client are in different network segments, a Relay device needs to be used. The Relay device can send a request message of the client to a DHCP server which is not in the same network segment, and send a response message of the DHCP server back to the client to complete IP address allocation.
Due to the continuity of the use of the client, after the client applies for the IP address in the DHCP, the DHCP server stores the corresponding relation between the client and the IP address, and when the client applies for the IP address again, the DHCP server reallocates the IP address stored before to the client.
However, with the development of networks and information technologies, in some scenarios, a client wants to obtain a new IP address every time the client goes online, and how to satisfy the requirement that the client in the above scenario can obtain a new IP address when the client goes online again becomes a problem to be solved urgently.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment of the invention provides a client IP address allocation method and device, which are used for realizing that a client can obtain a new IP address when the client is on-line again.
First, a method for allocating an IP address of a client according to an embodiment of the present invention is described below.
The method for allocating the client IP address provided in the embodiment of the present invention may be applied to a Relay device in a dynamic host configuration protocol DHCP network, and as shown in fig. 1, may include the following steps:
s101: receiving an IP address allocation request sent by a client, wherein the IP address allocation request carries identification information of the client;
the IP address allocation request may be a discover message, and the identification information may include a Media Access Control (MAC) address and IDentity (ID) information of the client.
S102: searching a corresponding relation table stored locally according to the identification information, wherein the corresponding relation table stores the corresponding relation between the identification information of the client and a first IP address allocated to the client by a DHCP server;
it is understood that when the Relay device receives an IP address allocation request sent by a client, the identification information of the client can be recorded. The Relay device has pre-stored a corresponding relationship between the identification information of the client and the first IP address allocated by the DHCP server for the client, and the corresponding relationship between the client and the first IP address may be recorded in the last IP address allocation. And matching the client from the stored corresponding relation table according to the identification information of the client carried by the IP address allocation request after the Relay equipment receives the IP address allocation request of the client, wherein the matching is successful when the corresponding relation between the identification information of the client and the first IP address allocated to the client by the DHCP server is stored in the Relay equipment. And when the matching is successful, performing the subsequent client IP address allocation process.
S103: when a target table entry containing a first IP address is matched, sending an address conflict message carrying the first IP address to a DHCP server so that the DHCP server records the first IP address as a conflict address;
after the target table entry containing the first IP address is matched, in order to avoid that the IP address requested by the client at this time is the same as the first IP address, before the Relay equipment forwards the IP address allocation request, the client is simulated to send an address conflict message to the DHCP server. After receiving the address conflict message, the DHCP server records the first IP address as a conflict address, such as: and putting the first IP address into a conflict table, and not allocating the first IP address to any client within a preset time. The address conflict message may be a decline message.
S104: and sending the IP address allocation request to a DHCP server so that the DHCP server allocates a second IP address different from the first IP address to the client.
The Relay device sends the IP address allocation request to the DHCP server according to the prior art. The DHCP server will assign a second IP address to the client that is different from the first IP address.
By applying the embodiment of the invention, the Relay equipment receives an IP address allocation request which is sent by a client and carries identification information of the client; searching a corresponding relation table stored locally according to the identification information, wherein the corresponding relation table stores the corresponding relation between the identification information of the client and a first IP address allocated to the client by a DHCP server; when a target table entry containing a first IP address is matched, sending an address conflict message carrying the first IP address to a DHCP server so that the DHCP server records the first IP address as a conflict address; and sending the IP address allocation request to a DHCP server so that the DHCP server allocates a second IP address different from the first IP address to the client. Therefore, when the client re-online sends the IP address allocation request, the Relay device may send the address conflict message for the first IP address historically allocated to the client, so that the DHCP server can allocate a second IP address different from the first IP address historically allocated to the client, so that the client can obtain a new address when re-online.
In addition, the embodiment of the invention is only improved for the Relay device, and the random address allocation function is configured for some predetermined interfaces, so that the client side through the predetermined interfaces can obtain the randomly allocated IP addresses. The DHCP server is not modified, the existing protocol mechanism is used, and the compatibility and the real-time performance are good.
In a specific implementation manner, a plurality of interfaces are configured in the Relay device to access the client. In the embodiment of the invention, a random address allocation function is configured on some preset interfaces of the Relay equipment, and the configured random address allocation function is controlled by a switch, so that only a client of the interface with the random address allocation function being started can be allocated with an IP address different from a historically allocated IP address. The searching for the locally stored corresponding relation table according to the identification information (S102) includes:
judging whether an interface corresponding to the client side starts a random address distribution function or not;
if yes, searching a corresponding relation table stored locally according to the identification information;
otherwise, the IP address allocation request is sent to the DHCP server.
It can be understood that, after it is determined that the function of randomly allocating an address of an interface corresponding to a client is turned on, the client may be determined to be a client that requires a randomly allocated address. And then performing a subsequent client IP address assignment procedure. When the random address allocation function of the interface corresponding to the client is judged to be not started, the client can be determined not to be the client requiring random address allocation, and an IP address allocation request can be directly sent to a DHCP server for IP address allocation.
In one specific implementation, for the client, there is a need for random address allocation in some specific scenarios, such as: playing a webgame, etc. However, other scenarios outside of the certain specific scenarios may not require random assignment of addresses. Further, the method for allocating the IP address of the client provided in the embodiment of the present invention may further include:
and when the random address distribution function of the interface corresponding to the client is closed, deleting the target table entry corresponding to the client.
Wherein, the target table entry records the corresponding relationship between the client and the first IP address allocated by the DHCP server for the client.
In a specific implementation manner, the method for allocating an IP address of a client provided in the embodiment of the present invention may further include:
receiving a release request sent by a client;
forwarding the release request to a DHCP server.
When a client needs to release a currently used IP address, after receiving a release request sent by the client, the Relay equipment forwards the address release according to the prior art and sends the address release to the DHCP server. In addition, when the client continues to make an order for the currently used IP address, the Relay device forwards the address continuation according to the prior art after receiving the address continuation sent by the client, and sends the address continuation to the DHCP server. In a specific application, the address continuation may be a Request message, and the address Release may be a Release message.
In a specific implementation manner, based on the flow shown in fig. 1, as shown in fig. 2, after the sending the IP address allocation request to the DHCP server (S104), the method for allocating an IP address of a client provided in the embodiment of the present invention may further include:
s201: receiving an address allocation response sent by the DHCP server aiming at the IP address allocation request;
s202: updating the target table entry in the corresponding relation table according to the second IP address carried in the address allocation response;
s203: and sending the second IP address to the client.
It should be noted that, in order to save the storage space of the Relay device, only the latest IP address allocated by the DHCP server to the client may be stored in the correspondence table, and each time the IP address allocated by the DHCP server to the client is received, the stored IP address is updated to the IP address allocated this time. Namely, the IP address contained in the target table entry is modified to the IP address allocated this time (the second IP address).
It can be understood that, when the interface of the Relay device corresponding to the client opens the function of randomly allocating an address, the Relay device receives the IP address allocation request sent by the client for the first time, that is, records the identification information of the client, at this time, the Relay device directly forwards the IP address allocation request sent by the client for the first time to the DHCP server, so that the DHCP server sends an address allocation response to the IP address request, and after receiving the address allocation response sent by the DHCP server to the IP address allocation request, the Relay device correspondingly records the first IP address allocated to the client carried in the address allocation response, and sends the first IP address allocated to the client carried in the address allocation response to the client. When the Relay device receives the IP address allocation request sent by the client again, the client IP address allocation method provided by the embodiment of the present invention is started to be executed, so that the DHCP server randomly allocates a second IP address different from the first IP address to the client.
Corresponding to the foregoing method embodiment, an embodiment of the present invention provides a client IP address allocation apparatus, which is applied to a Relay device in a dynamic host configuration protocol DHCP network, and as shown in fig. 3, the apparatus includes: a receiving module 301, a searching module 302 and a sending module 303;
the receiving module 301 is configured to receive an IP address allocation request sent by a client, where the IP address allocation request carries identification information of the client;
the searching module 302 is configured to search a locally stored mapping table according to the identification information, where the mapping table stores a mapping relationship between the identification information of the client and a first IP address allocated by a DHCP server to the client;
the sending module 303 is configured to send an address conflict message carrying a first IP address to a DHCP server when a target entry including the first IP address is matched, so that the DHCP server records the first IP address as a conflict address;
the sending module 303 is further configured to send the IP address allocation request to the DHCP server, so that the DHCP server allocates a second IP address different from the first IP address to the client.
By applying the embodiment of the invention, the Relay equipment receives an IP address allocation request which is sent by a client and carries identification information of the client; searching a corresponding relation table stored locally according to the identification information, wherein the corresponding relation table stores the corresponding relation between the identification information of the client and a first IP address allocated to the client by a DHCP server; when a target table entry containing a first IP address is matched, sending an address conflict message carrying the first IP address to a DHCP server so that the DHCP server records the first IP address as a conflict address; and sending the IP address allocation request to a DHCP server so that the DHCP server allocates a second IP address different from the first IP address to the client. Therefore, when the client re-online sends the IP address allocation request, the Relay device may send the address conflict message for the first IP address historically allocated to the client, so that the DHCP server can allocate a second IP address different from the first IP address historically allocated to the client, so that the client can obtain a new address when re-online.
In a specific implementation manner, the searching module 302 is specifically configured to determine whether an interface corresponding to the client starts a random address allocation function;
if yes, searching a corresponding relation table stored locally according to the identification information;
otherwise, the sending module 303 is triggered to send the IP address allocation request to a DHCP server.
