Problems solved by technology

[0004] However, in the way of passively capturing DNS data packets, it is first necessary to select DNS data packets from a large number of captured data packets, and the domain names collected each time are not fixed, so there is a long collection period for effective domain name information and storage of key domain name information.

Embodiment Construction

[0030] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

[0031] Please refer to figure 1 , is a schematic diagram of the domain name backup system provided by the embodiment of the present application. The domain name backup system includes a plurality of detection nodes 110, and the plurality of detection nodes 110 are connected to a server storing domain name information ( figure 1 Shown in the domain name server) communication connection. Wherein, the detecting node 110 may be a server.

[0032] Wherein, the domain name server is a server storing a domain name, such as a domain name, "example.com".

[0033] The domain name backup system can be an independent system set up separately from the domain name system of the Internet, or can be a part integrated in the domain name system of the Internet. When the domain name system is normal, generally spea...

Abstract

The invention provides a domain name backup method and device and a readable storage medium. The domain name backup method is applied to any detection node in a domain name backup system, and comprises the following steps: acquiring key domain names in a preset key domain name list; generating a domain name request data packet corresponding to the key domain name; sending the domain name request data packet to a domain name server according to a preset time period; when an effective response data packet sent by the domain name server is received, analyzing the effective response data packet to obtain domain name information corresponding to the key domain name; and storing the domain name information corresponding to the key domain name. The backup method is used for realizing effective backup of domain names.

Description

technical field [0001] The present application relates to the technical field of the Internet, in particular, to a domain name backup method and device, and a readable storage medium. Background technique [0002] DNS (Domain Name System, Domain Name System) can realize mutual mapping between domain names and IP (Internet Protocol, Internet Protocol) addresses, and is the basis for the normal operation of the Internet. However, the domain name system relies on the domain name resolution of the root server. If the root server cannot provide domain name resolution, Internet access will be paralyzed. [0003] In the prior art, the domain name information is backed up by passively capturing DNS data packets; or the root domain name system based on the alliance blockchain is used to ensure that the Internet can still be accessed normally after the existing domain name system service is paralyzed. [0004] However, in the way of passively capturing DNS data packets, it is first n...
