Abstract

Embodiments of the present invention provide a method and device for recovering Internet protocol addresses. The method includes: the online client receives a forced offline message carrying an encryption key sent by the server; wherein, the forced offline message is used to request the online client to go offline, and the IP address used by the online client is the first IP address; the online client decrypts the encryption key in the forced offline message according to the encryption algorithm to obtain the first key; the online client judges whether the first key matches its own second key and obtains the judgment result ; The online client determines whether to go offline and whether to send a DHCP RELEASE message to the server according to the judgment result. The method provided by the embodiment of the present invention makes the online client go offline immediately after the server reclaims the IP address used by the online client, thereby preventing the server from distributing the IP address to other clients again without causing IP Address conflict reduces IP address overhead.

Description

technical field [0001] The embodiments of the present invention relate to communication technologies, and in particular to a method and device for recovering Internet protocol addresses. Background technique [0002] With the expansion of the network scale and the improvement of network complexity, the network configuration becomes more and more complex, coupled with the sharp increase in the number of computers and the location is not fixed (such as mobile laptops or wireless networks), triggering the user's Internet protocol ( Internet Protocol, hereinafter referred to as IP) addresses frequently change and IP addresses are insufficient. In order to realize that the network can dynamically and reasonably allocate IP addresses to users, the Dynamic Host Configuration Protocol (Dynamic Host Configuration Protocol, hereinafter referred to as DHCP) application came into being. DHCP is a technology for centralized dynamic management and configuration of user addresses. It adop...
