How often have you tried to access a site only to get redirected to another page or even a completely different domain?
This happens because your computer has the wrong IP address assigned to it. If you don’t change it, you won’t be able to connect to the website anymore.
The Internet was designed to allow anyone to publish information freely. Unfortunately, this openness also makes it vulnerable to attacks from hackers who want to steal data or disrupt services. One way they do this is through DNS security bypasses.
DNS stands for Domain Name System. It allows computers to communicate using names instead of numbers (IP addresses).
When you type a web address into your browser, your computer sends a request to the DNS server asking for the IP address of the website you want to visit. The proper IP address is then returned by the DNS server.
The Problem:

DNS Security Bypass:
The (DNS) is a hierarchical naming system for computers, services, and other resources that are linked to the internet or a private network.

DNS Security Bypass In Google Chrome:
