Embodiment Construction

[0034] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not constitute a conflict with each other.

[0035] Such as figure 1 Shown, provide the embodiment of a kind of IPv6 address assignment method, comprise steps:

[0036] S1. The client sends an RS message and a DHCPv6 request message. In the RS message, two tags are newly added, one is used to identify the enabling state of the self-adaptive function, and the other is used to identify a preferred address allocation method. The DHCPv6 req...

Abstract

The invention discloses an IPv6 address allocation method and system, and relates to the technical field of communication. The method comprises the following steps that a client sends a routing request RS message and a DHCPv6 request message, and two marks are newly added in the RS message, wherein one mark is used for identifying the enabling state of an adaptive function, the other mark is used for identifying an inclined address allocation mode, and the DHCPv6 request message comprises specific information to be requested; the server replies a routing advertisement (RA) message and a DHCPv6 response message, and a mark indicating whether to respond to an address allocation mode which the client tends to is newly added in the RA message; and the DHCPv6 response message and the RA message both carry DNS information. According to the invention, the problems that the IPv6 address allocation mode is not flexible enough and has compatibility are solved.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to an IPv6 address allocation method and system. Background technique [0002] The existing IPv6 ((Internet Protocol Version 6, Internet Protocol Version 6) address allocation methods include stateful and stateless. According to the DHCPv6 (Dynamic Host Configuration Protocol)\SLAAC (Stateless Address Automatic Configuration) defined in RFC3315\RFC2462 ) mechanism. That is, the IPv6 address configuration is completed through DHCPv6 protocol interaction and ICMPv6 (Internet ControlMessage Protocol version 6, Internet Control Message Protocol version 6) routing notification. The processes and examples of the two address acquisition methods are as follows: [0003] (1) Obtain IPv6 address statefully [0004] The IPv6 address server sends a route notification message (ICMPv6 RA M=1) to notify all hosts in the environment that the current server configuration is a statefu...
