Abstract

The invention relates to a domain name verifying method which includes the following steps: monitoring a domain name resolution service, and capturing returned information before the domain name resolution service is returned, wherein the information comprises a domain name and an IP address list; obtaining a domain name list to be verified; judging whether the domain name in the information exists in the domain name list or not, and if the domain name in the information exists in the domain name list, submitting the domain and the IP address list which are included in the information to a verifying module for verifying; continuously returning the information if the information for expressing that verifying is successful is received. The invention further provides a domain name verifying device and system. By means of the domain name verifying method, device and system, the validity of the IP address list obtained through the domain name resolution service can be verified.

Description

technical field [0001] The invention relates to the field of network communication, in particular to a domain name verification method, device and system. Background technique [0002] Internet service providers usually announce to users the domain names that they provide Internet services. Users can obtain the IP address list of the server corresponding to the domain name through the domain name resolution service of the Domain Name System (DNS), and then request services from the server. If the local hosts file is configured with a list of IP addresses corresponding to the domain name, you can also directly read the local hosts file to obtain the list of IP addresses of the servers corresponding to the domain name. However, if the domain name server is attacked and implanted with wrong resolution information, the domain name system is tampered with, or the hosts file is tampered with, the user will get a wrong IP address list after entering the domain name, and there will...
