AI Technical Summary

Technical Problem

In existing technologies, when a client accesses a mobile domain name resolution service, network anomalies or server failures can cause the resolution result to be empty, affecting the stability and availability of the domain name resolution service.

Method used

Configure a local domain name cache on the client side to cache historical domain name resolution information, and retrieve the results from the online domain name resolution service when no results are found in the local cache. This ensures that domain name resolution information can still be obtained even when the network conditions are poor, thus avoiding empty results.

Benefits of technology

It improves the stability and availability of domain name resolution services, prevents domain name hijacking, and ensures the normal use of client services.

Abstract

The application provides a domain name resolution method and device, electronic equipment and readable medium. The method comprises: obtaining a domain name resolution request initiated by a client for a to-be-resolved domain name; searching for domain name resolution information of the to-be-resolved domain name in a local domain name cache according to the domain name resolution request, wherein the domain name resolution information in the local domain name cache is obtained from an online domain name resolution service according to historical domain name resolution requests; if the domain name resolution information of the to-be-resolved domain name is not found in the local domain name cache, sending the to-be-resolved domain name to the online domain name resolution service to obtain the domain name resolution information of the to-be-resolved domain name from the online domain name resolution service; and sending the domain name resolution information of the to-be-resolved domain name to the client and updating the domain name resolution information of the to-be-resolved domain name in the local domain name cache. The method can avoid the service of the client being unable to be normally used due to the return result of the domain name resolution being empty, prevent domain name hijacking, and improve the stability and availability of the domain name resolution service.
