Embodiment Construction

[0032] The present invention will be described in detail below in conjunction with various embodiments shown in the drawings. However, these embodiments do not limit the present invention, and changes in structures, methods or functions made by those skilled in the art based on these embodiments are all included in the protection scope of the present invention.

[0033] It should be noted that in different implementations, the same symbols or signs may be used, but these do not represent an absolute relationship in structure or function. Moreover, the "first" and "second" mentioned in the various embodiments do not represent an absolute distinction in structure or function, and these are merely for the convenience of description.

[0034] For authoritative DNS servers, they are the DNS servers that actually hold and are responsible for DNS resource records. This is the most source server in the DNS lookup chain, it will respond with the resource record of the query, and final...

Abstract

The invention discloses an authoritative DNS (Domain Name System) server information updating method and system. The method comprises the following steps: receiving a first information updating recordwhich comprises first content and first authorization information for carrying out the information updating of a first object; verifying the first authorization information, and determining the firstinformation update record as a to-be-packaged record when verification succeeds; and negotiating an accounting right with other authoritative DNS servers in the co-governance group according to a consensus rule, putting the record to be packaged into a new block when the accounting right is obtained, and synchronizing the record to be packaged to other authoritative DNS servers in the co-governance group. According to the invention, the dependence of DNS service on centralized management can be reduced, and the safety of the whole DNS system is improved.

Description

technical field [0001] The invention relates to the technical field of computer network communication, in particular to a method and system for updating authoritative DNS server information. Background technique [0002] DNS (Domain Name System, Domain Name System) provides an important service on the Internet, and its essence is to establish a bridge between the world of human names and the world of underlying binary protocol addresses. As a distributed database that maps domain names and IP addresses to each other, it can make it easier for people to access the Internet without having to remember the IP address strings that can be directly read by the machine, and finally get the corresponding IP of the domain name through the domain name The process of addressing is called domain name resolution. [0003] The domain name resolution process specifically initiates a query to the local domain name server in the form of a UDP (User Datagram Protocol, User Datagram Protocol) ...
