This document describes how to configure DNS hijacking test parameters for network quality, page performance, file download, and audio/video experience tasks in CAT.

Hijacking categories

Hijacking falls into two categories:
DNS hijacking: For example, if www.cloud.tencent.com is resolved to another server, user access will fail, or a non-Tencent Cloud IP will be returned.
Page tampering: JS, HTML, and HTTP headers of intermediate pages are used for redirects, window opening, or frameset embedding and then rendering of the hijacked page on the user side. Common forms are pop-up ads, floating ads, redirects, etc.
DNS hijacking monitoring parameter format:
Input: www.cloud.tencent.com:202.0.3.55|203.3.44.67
Rule:
The part before the colon is the target domain.
The part after the colon is the match rule.
You can set multiple match rules and separate them by vertical bar.
The exact IP, IP wildcard, subnet mask, and CNAME can be set in a match rule.
