DNS (Domain Name System, Domain Name System), a distributed database on the Internet that maps domain names and IP addresses to each other, enables users to access the Internet more conveniently without having to remember the IP that can be directly read by machinesnumber string.The process of obtaining the IP address corresponding to the host name through the host name is called domain name resolution (or host name resolution).The DNS protocol runs on top of the UDP protocol and uses port number 53.
The implementation process of visiting a web page:
From the user clicks the mouse, hits Enter, to the web page display, the information will first be sent through the browser, and then routed through the route
Transfer, then DNS resolves the domain name into IP, after finding the server, the server will send the content to the user, and then routed by the route
Forward the data, and finally the browser renders the content to the user.
Check if DNS is hijacked:
Once there is an error in DNS, it will not be able to resolve the domain name into the correct IP address, and we will naturally be unable to access it
The correct page, the target website opened is not the original content, but jumps to an unknown page, even if the terminal uses
Users who enter the correct URL will also be directed to those malicious websites.Therefore, if you find that the web page cannot be opened,
But the network software like QQ, which is directly connected to the IP, can serve normally, so DNS is a very doubtful reason.
DNS hijacking, also known as domain name hijacking.

Accelerated CDN can solve DDoS and CC attacks, and block hackers from scanning for program vulnerabilities.
How to fix DNS hijacking:

DNS server: 114.114.115.115 Click to confirm
Option 2: Use Tencent Computer Manager for DNS optimization
1. Open Tencent Computer Manager Toolbox
2. Find the DNS optimization function in the toolbox
3. Open DNS optimization for detection
