A multi-line intelligent resolution method of domain name based on radix tree

Abstract

The invention discloses a radix tree-based multi-line intelligent resolution method for domain names. The method realizes a brand-new BIND9 intelligent resolution scheme by borrowing the CLASS field in the DNS protocol family and simultaneously using the radix tree number to save the IP set corresponding to the line , the new solution only needs to configure a zone file for each domain name and is compatible with the old configuration. The IP address of the line can be dynamically increased or decreased, which solves the defects caused by the use of intelligent analysis when bind9 carries large data, so that it can be used without increasing the number of views. It supports intelligent parsing without adding zone files, and is compatible with old data, which can reduce hardware requirements and operation and maintenance technical requirements, and improve overall system performance.

Description

technical field

[0001] The invention relates to the technical field of domain name resolution, in particular to a radix tree-based multi-line intelligent domain name resolution method. Background technique

[0002] Facing today's big data era, the dns system adopts intelligent resolution, which can conveniently return different resolution addresses according to the network where the visitor is located, and get better services for load balancing, CDN accelerator, mirror website, dual-line computer room, etc. .

[0003] bind9 is a widely used dns system. In terms of intelligent resolution, the system uses multiple views. Each view provides separate resolution requests for different network environments. When the entire dns system carries a large amount of domain name resolution At this time, each line must define a VIEW, and each VIEW needs to define a new zone file. Whether it is an increase or decrease of the domain name, or a change of the IP address corresponding to the V...
