A dhcp configuration method and a dhcp client

Abstract

Embodiments of the present invention provide a DHCP configuration method and a DHCP client, which are applied in the field of local area network technology. In the REBINDING state, switch the DHCP client to the INIT state, so that the DHCP client enters the DHCP initialization process; if it is detected that the DHCP client has network switching, and when the state of the DHCP client is BOUND state, RENEWING state or REBOOTING state, Switch the DHCP client to INIT‑REBOOTING state, so that the DHCP client enters the fast DHCP initialization process. The embodiment of the present invention enables the DHCP client to quickly restore normal communication when network switching occurs at the DHCP client.

Description

technical field [0001] The invention relates to the technical field of local area networks, in particular to a DHCP configuration method and a DHCP client. Background technique [0002] With the vigorous development of computer technology and network technology, the application of network in all walks of life is more and more extensive. In the network, every networked computer needs to have an IP (Internet Protocol, Internet Protocol) address in order to communicate normally. IP Addresses are an important network resource. In a LAN, for most dial-up users, it is not advisable to assign a fixed IP address to each user due to the discrete time and space of the user's Internet access, which will cause a lot of waste of IP address resources. Therefore, a dynamic allocation method is usually used to allocate IP addresses to users. [0003] Among them, DHCP (Dynamic Host Configuration Protocol, Dynamic Host Configuration Protocol) is usually applied in a large-scale LAN environm...

Problems solved by technology

[0005] Therefore, if a network switch occurs on the DHCP client and the network switch occurs on the DHCP server, then the DHCP client may not continue to use the original IP address with a high probability, and the DHCP client cannot obtain a new IP address in time. As a result, the DHCP client that has undergone network switching cannot communicate normally within a certain period of time.
