Problems solved by technology

For example, KerioWmRoute Firewall version 6.0.10, released on March 22, 2005, they can only achieve the role of DNS message intermediary, and cannot realize the cross-proxy of multiple network protocols

Embodiment Construction

[0058] At present, the Internet is in the transition period from the IPv4 protocol to the IPv6 protocol migration, which just meets the applicable environment requirements of the present invention, such as figure 2 shown, namely

[0059] 1. There are network nodes N that are compatible with both IPv4 / IPv6 protocols, but they cannot encapsulate the same type of DNS messages with these two network protocols, and they can only use a certain network protocol to encapsulate this type of DNS message. DNS messages and DNS messages of another protocol type. In the figure, network node N is a Windows XP SP2 (Release 2005.04) host, compatible with IPv4 / IPv6 network protocols, but only provides IPv4 protocol to encapsulate DNS messages, that is, encapsulates A, AAAA and A6 with IPv4 network protocol These three types of DNS messages.

[0060] 2. In addition, there are also such DNS servers D, such as some specific configuration Linux servers, although they support IPv4 network protoco...

Abstract

The invention belongs to computer network interconnection technical field, relating to a method for implementing DNS service proxy in multiple-network protocol environment, using the character that DNS message can be packed by multiple network protocols to solve the problem that network node does not support DNS package of partial network protocols. By appointed multiprotocol DNS proxy S, it can make whichever protocol pack the needed-type DNS request as needing DNS and sends the request to S; S repacks the request according to the protocol type of the request and sends the repacked request to specific server and returns result to the node. For special condition that the network node has not implemented DNS package by any protocol, it installs S at the network node to capture all network connection requests: if destination is domain name request, resolving the domain name into network address, and S has domain name resolution buffer area to raise resolution efficiency.

Description

technical field [0001] The invention relates to the technical field of computer network interconnection, in particular to a method for realizing DNS service proxy in an environment where multiple network protocols exist. Background technique [0002] DNS (Domain Name Service, domain name resolution service) is a very important key technology in the field of computer network interconnection technology. It converts domain names that are easy to remember, use and manage into network addresses (such as IPv4 addresses or IPv6 addresses) used by network nodes such as computers. address), or vice versa. DNS service proxy technology is a transit technology for DNS requests and responses. By using DNS service proxy technology, network node groups can enjoy nearby services and improve efficiency. [0003] There are situations in which multiple network protocols are used in computer network interconnection (such as the coexistence of IPv4 and IPv6), and network nodes are also compatib...
