Abstract

The invention provides a CDN scene judgment method based on large content website DNS analysis. The CDN scene judgment method comprises the following steps of: 1, collecting global public DNS server IPs of a plurality of sources, and screening to obtain effective open DNS server IPs; 2, acquiring a target number of large content service websites by utilizing a web crawler technology; and 3, based on the effective open DNS server IP, acquiring the IP corresponding to the large content service website, and performing CDN scene determination on the acquired IP. According to the CDN scene judgment method, based on the globally open DNS server, all the IPs used by the domain name of the large-scale content service website can be obtained and judged as the IPs of the CDN scene, so that comprehensive judgment of the IPs of the CDN scene is realized.

Description

technical field [0001] The present invention relates to the field of IP application scene division, in particular, relates to a CDN scene judgment method based on DNS analysis of a large-scale content website. Background technique [0002] Large-scale content service websites often use CDN technology to enable users to obtain the desired content nearby, reduce network congestion, and improve user access response speed and hit rate. Currently, the IPs used by large content service websites are obtained by deploying detection machines around the world. However, this method is limited by the number and geographical distribution of detection machines, and cannot obtain all IPs used by large-scale content service websites, and cannot comprehensively determine global CND scene IPs. [0003] Therefore, it is necessary to propose a CDN scenario judgment method based on DNS analysis of large content websites, which can obtain the IP used by the domain name of large content websites ...
