But BOOTP has a disadvantage: you must obtain the hardware address of the client before setting, and the correspondence with the IP is static
Obviously, there are major limitations

Embodiment Construction

[0032] The specific implementation of the present invention will be further described in detail below in conjunction with the drawings and embodiments.

[0033] figure 1 is a schematic diagram of a network environment in an embodiment of the present invention, such as figure 1 As shown, the DHCP server and other servers, such as management server, mail server, file server, Web server, authentication server, etc. are integrated together.

[0034] figure 2 is another schematic diagram of the network environment of the embodiment of the present invention, such as figure 2 As shown, the DHCP server is independent from other servers. In this way, the DHCP message can be limited to a certain area to avoid affecting other services. In the embodiment of the present invention, the DHCP server assigns different addresses to the user according to the different attributes of the user before and after authentication, so that the user obtains different network services before and afte...

Abstract

The invention discloses a dynamic address allocation method for a dynamic host configuration protocol (DHCP) and a DHCP system. The method comprises the following steps that: a DHCP server manages mapping relationships between system configuration usernames or other attributes and media access control (MAC) addresses, or an external interface provided by the DHCP server inputs the mapping relationships between the usernames or the other attributes and the MAC addresses; and the DHCP server receives an address allocation request message, associates a MAC address carried by the request message with a username or attribute information which is obtained in advance, and searches for a given Internet protocol (IP) address for allocation according to the associated username or attribute information to realize user-based dynamic IP address allocation. By the method provided by the invention, the address can be allocated according to the user attribute under the condition of no additional requirements on a DHCP client and intermediate switching equipment, and on-demand address allocation is made possible; and the method is highly extensible.

Description

technical field [0001] The invention relates to the field of communication, in particular to a method for dynamic allocation of DHCP addresses, a method for realizing authentication through dynamic allocation of DHCP addresses and a DHCP system. Background technique [0002] DHCP is the abbreviation of Dynamic Host Configuration Protocol (Dynamic Host Configuration Protocol), and its predecessor is BOOTP. BOOTP was originally used on a network connected by a diskless host: the network host uses BOOT ROM instead of a disk to start and connect to the network, and BOOTP can automatically set the TCP / IP environment for those hosts. But BOOTP has a disadvantage: you must obtain the hardware address of the client before setting, and the correspondence with the IP is static. In other words, BOOTP is very "dynamic". DHCP can be said to be an enhanced version of BOOTP, which is divided into two parts: one is the server side, and the other is the client side. All IP network setting...
