Method for allocating and configuring address, address allocation server and host machine

Abstract

The invention provides a method for allocating and configuring an address, an address allocation server and a host machine. In the method, the address allocation server receives an internet protocol (IP) address request message sent by the host machine, wherein the IP address request message carries information for reflecting the physical address of the host machine, and the physical address of the host machine is network segment information and / or virtual local area network (LAN) identification which is allocated to the host machine for independent use by an IP load-carrying network; the address allocation server queries the IP address request message so as to acquire the physical address of the host machine; the address allocation server determines an IP address which is allocated to the host machine in accordance with a correspondence between an IP address maintained by the address allocation server and the physical address of the host machine; and the address allocation server allocates the determined IP address to the host machine. According to the embodiment of the invention, the problem that the physical address is configured by a person can be avoided, thereby ensuring that the IP address is allocated successfully based on the physical address.

Description

technical field [0001] The invention relates to communication technology, in particular to an address allocation and configuration method, an address allocation server and a host. Background technique [0002] In a communication system, the physical address is the root of identifying a device node, and any other technology for identifying the device node is derived from the physical address. For example, in Ethernet communication, the Media Access Control (MAC) address is the physical address of the device node and can be used for Ethernet local communication; the IP address is a logical address mapped from the MAC address and used for Internet communication . In the prior art, an electronic serial number (Electronic Serial Number, ESN) may be used as a physical address, or a MAC address may be used as a physical address. Regardless of whether it is an ESN or a MAC address, equipment manufacturers record these physical addresses on the communication equipment. When users ...
