Hosts File… what?
The computer file hosts is an operating system file that maps hostnames to IP addresses. It is a plain text file. ”hosts (file)”, Review on Wikipedia
Whenever your browser interacts with a website, it actually requests a server, located through its IP address, like 185.31.40.11 (IPv4) or 2a00:b6e0:1:20:2::1 (IPv6). It’s pretty similar to a postal address.
Now think about accessing a webpage, like https://wincpr.com How does your browser know which IP address to contact? Well, the browser simply asks the Internet phone book. At least, one of them. And the phone book, called a DNS, resolves the IP address for the browser.
