Abstract

The present invention provides a method, primary Domain Name System(DNS) server, secondary DNS server and domain name system for realizing synchronization of the DNS zone creation, wherein the method includes: the primary DNS server creates a DNS zone and sets the dependence relationship between each DNS server in the DNS zone, and each DNS server includes a primary DNS server and at least two levels of secondary DNS servers(11); according to the dependence relationship, the primary DNS server sends to the secondary DNS servers level by level a notification message including the information of the higher-level server of the secondary DNS servers, until each secondary DNS server has recorded the information of the higher-level server which each secondary DNS server belongs to, and has obtained the zone file from each higher-level server according to the notification message(12). The defect of the prior art that when the DNS server creates a new DNS zone, the DNS administer needs to execute manual update on the zone file corresponding to the newly created DNS zone and the higher-level server information of the secondary DNS server in the secondary DNS server is changed, and thus when the DNS server creates a new DNS zone, an automatic update is realized.

Description

technical field

[0001] The embodiment of the present invention relates to the technical field of domain name system, and in particular to a method for synchronizing DNS zone creation, a primary DNS server, a secondary DNS server, and a domain name system. Background technique

[0002] The Domain Name System (Domain Name System; hereinafter referred to as DNS) is a distributed database that can map domain names and Internet Protocol (Internet Protocol; hereinafter referred to as IP) addresses to each other. DNS is stored on DNS servers distributed all over the world. DNS servers include primary master server and secondary server. Wherein, the main server refers to the server that stores the relevant files of the authorized zone (Zone), and is the most fundamental source of domain (Domain) information. It is the source of domain transfers for all secondary servers; the primary server reads domain data from local hard disk files. The secondary server, also known as the second...
