It should also be understood that, although the present disclosure has been described with reference to some specific examples, a person skilled in the art will certainly be able to achieve many other equivalent forms of the present disclosure, having the characteristics as set forth in the claims and hence all coming within the field of protection defined thereby.

Well-known and/or repeated functions and constructions are not described in detail to avoid obscuring the disclosure in unnecessary or unnecessary detail. Therefore, specific structural and functional details disclosed herein are not intended to be limiting, but merely serve as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present disclosure in virtually any appropriately detailed structure.
The specification may use the word "in one embodiment," "in another embodiment," "in yet another embodiment," or "in other embodiments," which may each refer to one or more of the same or different embodiments in accordance with the disclosure.
In a first aspect, for ease of understanding the present disclosure, a method for recovering an internet protocol address provided by the present disclosure is first described in detail. As shown in fig. 1, in the recovery method provided in the embodiment of the present disclosure, according to the method steps shown in fig. 1, the problem that in the prior art, when a network is temporarily disconnected or a user terminal is not started or is not connected to the network, an IP address is erroneously recovered, so that the accuracy of a detection result is low, and after the IP address is erroneously recovered, an original user terminal corresponding to the recovered IP address cannot access the network, resulting in resource waste is solved. The specific steps include S101-S104.
S101, acquiring and responding to the recycling instruction, and sending a plurality of detection messages to each Internet protocol address according to the time interval.
In an implementation, the reclamation instruction is acquired in real time and/or periodically, and after the reclamation instruction is acquired, the reclamation instruction is responded to, that is, the detection of the internet protocol address is started. Optionally, after acquiring the reclamation instruction, sending a plurality of detection messages to each internet protocol address according to a time interval. That is, for each internet protocol address, a plurality of detection messages are sent, and a certain time interval exists between the sending time of two adjacent detection messages, so that the problem that when only one detection message is sent, the current network is temporarily disconnected or the current network is not started or connected, so that a response message of the user terminal cannot be received is avoided, and the problem that the internet protocol address is recovered by mistake in the follow-up is avoided.
It is worth noting that in the case where no reclamation instruction is obtained, no probing of the internet protocol address is performed.
Optionally, embodiments of the present disclosure provide for generating the reclamation instruction in two ways, the first way being: determining whether a preset period is reached, and generating a recycling instruction under the condition that the preset period is reached, namely setting a preset period for the current network, wherein the preset period is used for indicating to detect the internet protocol address in the current network. The preset period may be set to one week, three days, one month, etc., and as one example, the preset period is set based on the attribute of the current network, the number of accessed user terminals, etc., for example, in a scenario where the current network is an internal network of a company and the number of accessed user terminals is relatively fixed, the preset period may be set to be relatively long, such as one month; in the scenario that the current network is a public network and the change frequency of the accessed user terminal is high, the preset period can be set to be short, such as three days.
The second way to generate the recycling instruction provided by the embodiments of the present disclosure is: it is determined whether an address allocation request is received, wherein the address allocation request is sent by a new user terminal that is not accessing the current network, that is, there is a new user terminal requesting access to the current network. Further, in the case of receiving the address allocation request, generating a reclamation instruction, and as one example, in the case of receiving the address allocation request, further determining whether the unallocated internet protocol address in the current network meets a second condition, where the second condition is that a proportion of the unallocated internet protocol address to all internet protocol addresses is smaller than a preset proportion, where the preset proportion is a proportion of an internet protocol address which cannot be allocated to a new user terminal in the current network to all internet protocol addresses, where the preset proportion is determined based on an attribute of the current network, for example, in a case that a bandwidth of the current network is larger, the preset proportion may be set smaller; in the scene of smaller bandwidth of the current network, a larger preset proportion can be set, and the like. And then, after determining that the unassigned internet protocol address meets the second condition, namely, determining that the assignable internet protocol address in the current network is insufficient, generating a recycling instruction.
Of course, in the same network, the reclamation instruction may be generated only by the first manner or the second manner, or may be generated by the first manner and the second manner, which is not particularly limited in the embodiments of the present disclosure.
S102, determining whether a response message returned by a user terminal corresponding to each Internet protocol address meets a first condition according to each Internet protocol address, wherein the response message is obtained by the user terminal responding to the detection message, and the first condition is that the ratio of the first number of the response messages to the second number of the detection messages is smaller than a preset threshold.
And after sending a plurality of detection messages to each internet protocol address according to the time interval, receiving a response message returned by the user terminal corresponding to each internet protocol address in real time aiming at each internet protocol address.
After receiving a response message returned by a user terminal corresponding to the internet protocol address, determining whether the response message returned by the user terminal corresponding to the internet protocol address meets a first condition, wherein the response message is obtained by the user terminal responding to a detection message, the first condition is that the ratio of the first number of the response messages to the second number of the detection messages is smaller than a preset threshold, for example, the detection messages sent to the internet protocol address are set to be 5, the preset threshold is set to be 0.6, if the received response message is set to be 4, the ratio of the first number to the second number is set to be 4/5=0.8, and the ratio is larger than the preset threshold to be 0.6, so that the response message returned by the user terminal corresponding to the internet protocol address is determined to not meet the first condition; if the number of the received response messages is 2, the ratio of the first number to the second number is 2/5=0.4, which is smaller than the preset threshold value of 0.6, and further it is determined that the response message returned by the user terminal corresponding to the internet protocol address meets the first condition.
And S103, under the condition that the response message returned by the user terminal corresponding to the Internet protocol address meets the first condition, updating the current identification of the Internet protocol address, wherein the current identification represents the times that the response message returned by the user terminal corresponding to the Internet protocol address continuously meets the first condition.
And under the condition that the response message returned by the user terminal corresponding to the Internet protocol address meets the first condition, indicating that the user terminal corresponding to the Internet protocol address does not use the Internet protocol address, and updating the current identification of the Internet protocol address. The current identifier characterizes the times that the response message returned by the user terminal corresponding to the Internet protocol address continuously meets the first condition.
As one example, the current identifier is a numerical value, and when the current identifier of the internet protocol address is updated to obtain an updated identifier, 1 may be directly added to the current identifier to obtain an updated identifier, and then the updated identifier is used to update the current identifier, that is, the current identifier is modified to be the updated identifier.
And S104, determining whether to recycle the corresponding Internet protocol address based on the updated identification.
After the updated identifier is obtained, determining whether to recycle the corresponding internet protocol addresses according to the updated identifier, wherein as an example, the preset number of internet protocol addresses can be recycled according to the descending order of the times that the response messages returned by the user terminals corresponding to the internet protocol addresses continuously meet the first condition; optionally, the number of the received address allocation requests may be determined first, and then the internet protocol addresses of the number of requests may be recovered according to the descending order of the times that the response messages returned by the user terminals corresponding to the internet protocol addresses continuously meet the first condition, so as to achieve the purpose that the new user terminal accesses the current network.
In a specific implementation, when a response message returned by a user terminal corresponding to an internet protocol address does not meet a first condition, that is, a ratio of a first number of response messages to a second number of probe messages is greater than or equal to a preset threshold, that is, the user terminal corresponding to the internet protocol address uses the internet protocol address, it is determined whether a current identifier of the internet protocol address is a preset identifier. If it is determined that the current identifier of the internet protocol address is not the preset identifier, the current identifier of the internet protocol address is changed to the preset identifier, wherein the preset identifier characterizes that the internet protocol address is allocated, and for example, the preset identifier is set to 0.
After the updated identifier is obtained, an address allocation request is received in real time, and the address allocation request is responded, namely, the recovered internet protocol address is redistributed, so that the request of accessing the new user terminal into the current network is met.
After acquiring the recycling instruction, the embodiment of the disclosure transmits a plurality of detection messages to each internet protocol address according to a time interval in response to the recycling instruction so as to finish one-time detection of each internet protocol address, further determines whether a response message returned by a user terminal corresponding to each internet protocol address meets a first condition, and if so, updates a current identifier of the internet protocol address to obtain an updated identifier, so as to determine whether to recycle the corresponding internet protocol address based on the updated identifier, thereby avoiding the problem of incorrect recycling of the internet protocol address caused by temporary network disconnection or un-started and un-connected network of the user terminal, and improving the accuracy of detection results, namely recycling; and the original user terminal corresponding to the Internet protocol address can be ensured to normally use the network, and the resource waste is avoided.
