[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 i

Abstract

The invention discloses a domain name multiline intelligent analyzing method based on a radix tree. According to the method, through adoption of a CLASS field in a DNS protocol family and reservation of an IP set corresponding to a line by use of the radix tree, a brand new BIND9 intelligent analysis scheme is realized. In the novel scheme, each domain name only requires configuration of one zone file and is compatible with old configuration, the IP address of the line can be dynamically increased and decreased, the defect brought about by use of intelligent analysis when bind9 carries big data is well solved, the intelligent analysis is supported under the condition that neither views nor zone files are increased, compatibility with old data is realized, hardware requirements and operation and maintenance technological requirements can be reduced, and the overall system performance is improved.

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...
