Embodiment Construction

[0034] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but 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 there is no conflict with each other.

[0035] like figure 1 As shown, an embodiment of an IPv6 address allocation method is provided, comprising the steps of:

[0036] S1. The client sends an RS message and a DHCPv6 request message. In the RS message, two new flags are added, one is used to identify the enabled state of the adaptive function, and the other is used to identify the preferred address allocation method. The DHCPv6 request...

Abstract

An IPv6 address allocation method and system, relating to the technical field of communications, the method comprises that a client sends a routing request RS message and a DHCPv6 request message, and in the RS message, two new markers are added, and one identifies the enabled state of an adaptive function. , another address allocation method that identifies the preference; the DHCPv6 request message contains the specific information to be requested; the server replies to the route advertisement RA message and the DHCPv6 response message, and the RA message adds a new address assignment whether to respond to the client's preference In addition, DNS information is carried in both the DHCPv6 response packet and the RA packet. The invention solves the problems that the IPv6 address allocation mode is not flexible enough and has compatibility.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a method and system for assigning IPv6 addresses. Background technique [0002] The existing IPv6 ((Internet Protocol Version 6, Internet Protocol Version 6) address allocation methods include stateful and stateless two, according to the DHCPv6 (Dynamic Host Configuration Protocol) \SLAAC (Stateless Address Automatic Configuration) defined by the RFC3315\RFC2462 specification ) mechanism. That is, through the DHCPv6 protocol interaction and the ICMPv6 (Internet ControlMessage Protocol version 6, Internet Control Message Protocol version 6) routing advertisement coordination to complete the IPv6 address configuration. The process and examples of the two address acquisition methods are as follows: [0003] (1) Stateful acquisition of IPv6 addresses [0004] The IPv6 address server sends a route advertisement message (ICMPv6 RAM=1) to notify all hosts in the enviro...
