Abstract

The invention provides a method and device for locating and analyzing faults. It involves the Internet field; it solves the problems of inability to locate faults and inaccurate detection of faults. The method includes: collecting NXDOMAIN information; determining the authoritative domain name service DNS server involved in the collected NXDOMAIN information; obtaining current operating status information of the authoritative DNS server, and determining whether the authoritative DNS server fails according to the operating status information. The technical solution provided by the invention is applicable to DNS, and realizes efficient and accurate positioning of resolution failures.

Description

technical field [0001] The invention relates to the field of the Internet, in particular to a method and device for locating and analyzing faults. Background technique [0002] As the entrance of Internet access, DNS resolution occupies a very important position in the entire Internet system. How to ensure the stable operation of DNS is very important. [0003] "NXDOMAIN response" means "the resolved domain name does not exist". The result of resolving NXDOMAIN from the business service domain name due to failure is one of the most important DNS failures, which will directly lead to the inability to provide network services. [0004] The cause of the NXDOMAIN response is complex and involves many devices. According to the NXDOMAIN response, it is impossible to determine whether a fault has occurred, let alone locate the fault, and the detection of the fault is not accurate. Contents of the invention [0005] The present invention aims to solve the problems described abov...
