Embodiment Construction

[0022] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0023] The equipment used in the present invention is common equipment common in the market, and the required software is all open source software. The Bind used in the implementation is an open source DNS server software. Bind is developed and maintained by the University of California, Berkeley, and its full name is Berkeley InternetName Domain. It is currently the most widely used DNS server software in the world, supporting various unix platforms and windows platforms.

[0024] Configuration of multi-line smart DNS:

[0025] 1. Main domain name service module configuration. Install and deploy the BIND system on the main domain name service module, and perform a brief configuration. The following files are mainly configured in the BIND system. (1) Network segment IP configuration file. This file contains the IP network segments of four telecom operato...

Abstract

The invention discloses a multi-line intelligent DNS (Domain Name System) resolution device and method, and belongs to the field of communication so as to solve problems of line bottleneck and slow access caused by cross-network access. The multi-line intelligent DNS resolution device comprises an intelligent DNS device and a service site module, the intelligent DNS device is composed of a main domain name service module, an auxiliary domain name service module and a database service module, the main domain name service module and the auxiliary domain name service module are connected with the database service module, the database service module is connected with the service site module through the Internet, and the service site module is connected with telecom users, mobile users, Unicom users and education network users. The multi-line intelligent DNS resolution device returns different IP addresses according to different incoming paths on the main domain name service module, the auxiliary domain name service module and the database service module, and ensures the continuity and high availability of services. The multi-line intelligent DNS resolution device mainly has the advantages that 1) the real-time performance of domain name resolution is ensured; and 2) operations of domain name resolution are simplified.

Description

technical field [0001] The invention belongs to the field of communication, and in particular relates to a multi-line intelligent DNS analysis device and method. Background technique [0002] DNS (Domain Name System, Domain Name System) is a distributed database on the Internet that maps domain names and IP addresses to each other, enabling users to access the Internet more conveniently without having to remember IP numbers that can be directly read by machines. The process of finally obtaining the IP address corresponding to the host name through the host name is called domain name resolution (or host name resolution). [0003] The DNS protocol runs on top of the UDP protocol, using port number 53. There are two ways to map the host name to the IP address: 1) Static mapping, each device is configured with the mapping from the host to the IP address, and each device maintains its own mapping table independently, and it is only used by this device; 2) Dynamic mapping , esta...
