Embodiment Construction

[0038] Adopt the IP address distribution method that the present invention provides, receive the address request message that client sends by switch; Determine the location information of this client according to address request message; Obtain the corresponding relation of location information and network interconnection agreement IP address, according to The corresponding relationship determines the IP address corresponding to the location information of the client; and assigns the determined IP address to the client. In this way, an IP address can be dynamically assigned to the client according to the location information of the client, which can ensure that all clients connected to the network can be assigned an IP address, and the working efficiency of the DHCP server is improved.

[0039] The embodiment of the present invention provides a method for assigning an IP address, which is applied to equipment and devices implementing DHCP technology, such as a DHCP server. In t...

Abstract

The invention discloses an IP (internet protocol) address allocation method and device, and aims to solve the problem that a DHCP (dynamic host configuration protocol) server in the prior art is poor in universality, cannot allocate an IP address for each client and is low in working efficiency. The method includes the steps: receiving an address request message transmitted by an exchanger of the client; determining position information of the client according to the address request message; acquiring the corresponding relation between the position information and the IP address; determining the IP address corresponding to the position information of the client; transmitting the determined IP address to the client. Therefore, IP address allocation performed according to an MAC address of a network card of the client is avoided, the IP address can be dynamically allocated for the client according to the position information of the client, IP addresses can be allocated for all the clients accessing a network, and the working efficiency of the DHCP server is improved.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to an IP address allocation method and device. Background technique [0002] Dynamic Host Configuration Protocol (Dynamic Host Configuration Protocol, DHCP) is a LAN network protocol, which can dynamically assign Internet Protocol (Internet Protocol, IP) addresses to clients accessing the network. Configure the correspondence between the IP address and the Medium Access Control (MAC) address in , and after the client accesses the network, according to the MAC address of the network card of the client, search for the corresponding MAC address in the correspondence IP address and send it to the client. [0003] According to the correspondence between the IP address and the MAC address set by the DHCP server, assign an IP address to the client. In this correspondence, the MAC address of each network card needs to be set to the corresponding IP address. However, each clie...
