Embodiment 1

[0053] Embodiment 1, a method for realizing dynamic domain name update in an IPv6 network has the following steps:

[0054] Below is the description of the three stages of the program of the present invention;

[0055] Step 1: The DHCPv6 server and the client host interactively assign addresses;

[0056] According to rfc3315, the message format of the DHCPv6 protocol is: the first 4 bytes, which are 1 byte message type (msg-type) and 3 bytes transmission identifier (transaction-id), and the rest Sections all consist of different types of option fields. Currently, there are 29 option fields that have been determined by rfc according to different functions.

[0057] The inventive scheme proposes two types of options in the first stage:

[0058] Client Hostname Option

[0059] The specific format is as follows:

[0060] 0 1 2 3

[0061] 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1

Embodiment 2

[0110] Embodiment 2, the following is a detailed description of the three stages of the program of the present invention,

[0111] The first stage: the DHCPv6 server and the client host interact to assign addresses

[0112] The DHCPv6 protocol defines 13 packet types in total. Compared with DHCPv4, its protocol function has many extensions, but the working principle of the function of DHCPv6 protocol address allocation is roughly the same as that of DHCPv4.

[0113] In the first step, after the client host is connected to the network, if it needs one or more IPv6 addresses, it will first send a Solicit message to all DHCPv6 servers and relay agents to find an available server. The Solicit message uses Client The Identifier option field carries the DUID that identifies this client host.

[0114] In the second step, all DHCPv6 servers that receive the Solicit message will reply with an Advertise message. The Advertise message uses the Server Identifier option field to carry th...

Abstract

A method for realizing dynamic domain name refresh in IPv6 network includes three steps: 1, DHCPV6 server and the host of the customer end interact the assigned addresses, 2, DHCPv6 server and the customer end host interact the negotiated domain names, 3, DHCPV6 server and DNS server interact, which enables ordinary PC of mobile Ipv6 user to become a stable WEB server or FTP server at any time in the continuously switched IPv6 network to solve the problem of analyzing dynamic domains in IPv6 network.

Description

Technical field [0001] The invention relates to a method for realizing dynamic domain name update in an IPv6 network, belonging to the technical field of communication. Background technique [0002] The realization of Dynamic Domain Name Resolution (DDNS) is divided into two aspects, they are Domain Name System (DNS) and Dynamic Host Configuration Protocol (DHCP). [0003] The full name of DNS is Domain Name System (Domain Name System), which was proposed in 1984 by Paul Mockapetris, who was in charge of designing a new network architecture at the Institute of Information Science, University of Southern California. The original description of DNS was through RFC882 and 883, which were later superseded by RFC1034 and 1035. In effect, DNS is a distributed database that allows local control over various parts of the entire database. At the same time, the entire network can also access the data of each part through the client-server method. DNS first divides the entire networ...
