Problems solved by technology

[0007] In the existing dual-stack address allocation method, users have obtained IPv4 and IPv6 addresses before authentication, that is, for some unregistered users, or users who do not plan to use the WLAN service, as long as their terminals are associated with the AP, they can Obtaining IPv4 and IPv6 addresses intensifies the consumption of IPv4 addresses, resulting in a waste of addresses

Embodiment Construction

[0028] In view of the problems existing in the above-mentioned prior art, the embodiment of the present invention provides a dual-stack address allocation technical solution, which is applied to the address allocation process of a dual-stack user terminal. When the AC receives an IPv4 address acquisition request (DHCP discover (discovery) message), judge whether the user terminal is authenticated; if the user terminal is authenticated, assign an IPv4 address to the user terminal; otherwise, refuse to assign an IPv4 address to the user terminal. Through this technical solution, the allocation mechanism of IPv4 addresses can be optimized, and the consumption of IPv4 addresses can be saved.

[0029] The technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Apparently, the described embodiments are part of the embodiments of this application, not all of them. All other embodiments obtained by pe...

Abstract

The invention discloses a method and device for distributing double-stack addresses. The method includes: an access controller (AC) receives internet protocol v4 (IPv4) address acquisition requests sent by user terminals; the AC judges whether the user terminals pass through certification; if on yes judgment, the AC distributes IPv4 addressed to users; otherwise the AC refuges to distribute the IPv4 addresses to the user terminals. The method and device for distributing double-stack addresses optimizes an IPv4 address distribution mechanism and reduces consumption of the IPv4 addresses.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a dual-stack address allocation method and device. Background technique [0002] In the current WLAN (Wireless Local Area Network, wireless local area network) network based on IPv4 (Internet Protocol version 4, Internet Protocol version 4), the user terminal obtains a public IPv4 address through the DHCP (Dynamic host configuration protocol, dynamic host configuration protocol) protocol, thereby Gain Internet access. But it is well known that IPv4 addresses have been basically exhausted at present. [0003] At the same time, WLAN services are in a stage of rapid growth. In the next few years, the number of APs (Access Points, Access Points) will increase exponentially, and the number of WLAN service users will also increase exponentially, requiring a large number of IP addresses. Obviously, the IPv4 addresses that are about to be exhausted can no longer meet the ...
