Abstract
The invention provides a failure domain name detection method and device, and relates to the technical field of communication, and the method comprises the steps: firstly receiving a uniform resourcelocator (URL), sent by a user, of a to-be-detected webpage, and obtaining the webpage information of the to-be-detected webpage based on the URL; wherein the webpage information comprises at least oneof an IP address, a domain name, a title, a response code and a response body; if the IP address of the domain name cannot be resolved, determining the domain name of which the IP address can be resolved and the domain name is expired as a failure domain name; and if the IP address can be resolved and the domain name is not expired, determining whether the domain name is a failed domain name based on at least one of the title, the response code and the response body. According to the invention, all failure domain names in the recorded domain name data can be discovered in time, the detectionis comprehensive, the accuracy of failure domain name detection is improved, and great convenience is brought to supervision work.
Description
technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for detecting an invalid domain name. Background technique [0002] For regulatory agencies, the domain name data in a region can be counted, supervised and declared by using a large amount of domain name data collected. If the domain name data fails, it will bring serious inconvenience to the supervision work, that is, there may be false positives during use, which will easily lead to a decrease in data accuracy. Therefore, detecting invalid domain names becomes an indispensable task. [0003] Existing technology only detects invalid domain names whose IP addresses cannot be resolved based on whether the IP addresses can be resolved, but domain names whose IP addresses can be resolved still have the possibility of becoming invalid domain names, so the existing detection methods for invalid domain names are not comprehensive and accurate Low technical...
