Problems solved by technology

However, under the condition of using a single-node deployment structure, if WAN network fluctuations or network congestion occur, the network reachability of the service deployment node will become poor, which will lead to a sharp decline in the availability of WHOIS services
[0005] Therefore, there is a problem in the prior art that the availability of WHOIS services is affected due to the randomness and length of WAN network congestion.

Embodiment 1

[0062] Embodiment 1 is a disaster recovery switching method for domain name query service provided by the embodiment of the present invention, refer to figure 1 As shown, the method includes:

[0063] 101. Periodically monitor service availability of the main server.

[0064] 102. When it is monitored that the service availability of the main server is lower than the preset value, analyze the top-level domain name in the received domain name information query request, and obtain the disaster recovery server address corresponding to the top-level domain name.

[0065] Specifically, the process can be:

[0066] Determine the top-level domain name according to the domain name information carried in the domain name information query request;

[0067] Perform DNS resolution on the top-level domain name, and obtain the disaster recovery server address corresponding to the top-level domain name according to the DNS resolution result, and the address includes at least one of an IPv4...

Embodiment 2

[0078] Embodiment 2 is a method for disaster recovery switching of domain name query service provided by the embodiment of the present invention, refer to figure 2 As shown, the method includes:

[0079] 201. Generate index data according to the domain name registration information of the main server.

[0080] Among them, the main server is used to store the domain name registration information corresponding to the top-level domain. For the same top-level domain, it can be resolved to at least one main server. For example, if the top-level domain is .top, then the main server corresponding to the .top top-level domain can be IPv4_master and / or IPv6_master.

[0081] Domain name registration information includes at least one or more of domain name, registrar, registration agency, registrant, registrant email address, registration date, update date, expiration date, domain name status, and domain name server.

[0082] Specifically, the process may include:

[0083] Obtain the...

Embodiment 3

[0151]Embodiment 3 is a disaster recovery switching device for domain name query service provided by the embodiment of the present invention, refer to image 3 As shown, device 3 includes:

[0152] A receiving unit 31, configured to receive a query request for domain name information;

[0153] A monitoring unit 32, configured to periodically monitor the service availability of the main server;

[0154] The parsing and obtaining unit 33 is used to parse the top-level domain name in the received domain name information query request to obtain the disaster recovery server address corresponding to the top-level domain name when the service availability of the main server is monitored to be lower than a preset value;

[0155] The switching unit 34 is configured to switch the target server of the domain name information query request to the disaster recovery server according to the address of the disaster recovery server, so that the disaster recovery server provides domain name qu...

Abstract

The invention discloses a disaster recovery switching method and device for a domain name query service, belonging to the technical field of Internet security. The method includes: periodically monitoring the service availability of the main server; when the monitored service availability of the main server is lower than a preset value , analyze the top-level domain name in the received domain name information query request, and obtain the disaster recovery server address corresponding to the top-level domain name; switch the target server of the domain name information query request to the disaster recovery server according to the disaster recovery server address, so that The disaster recovery server provides domain name query services. The present invention switches the target server of the domain name information query request to the disaster recovery server, so that the disaster recovery server provides the domain name query service, thereby reducing the impact on the availability of the WHOIS service due to the randomness and length of the wide area network congestion. .

Description

technical field [0001] The invention relates to Internet security technology, in particular to a disaster backup switching method and device for domain name query service. Background technique [0002] WHOIS is a database used to query whether a domain name has been registered and the details of the registered domain name. Domain name information can be queried through WHOIS. For example, a domain name registrar needs to confirm whether the domain name data has been correctly registered in the domain name registration center, and often queries through WHOIS; for example, when many Internet users surf the Internet, they hope to learn more about The detailed information of the domain name will also be queried through WHOIS at this time. Intuitively, WHOIS is a search engine linked to a domain name database. The WHOIS information of each domain name / IP is kept by the corresponding management agency; the WHOIS information of different domain name suffixes needs to be queried i...
