How does www.something.com work?

Question

Domain Name System

What is this site and how does it work?


This site was created on 1995-07-28 and last updated on 2019-04-27 and has ip 127.0.0.1. Can there be such an IP at all or is it being redirected? After looking for some more sites, I came across the same tiretipsqa.com, which is also being redirected. The question is why such sites are made and how do they work? You can also do a redirect, let's say to 192.168.0.1 in this way.

Was it difficult to check?)
Well, yes, they do not work. It's just that someone tested them locally without knowing about the hosts file
