What Is Hosts File
Whenever you want to open any website on your computer using the Internet, you type the URL or address of the website, which is also known as the domain name, such as www.talkwidtech.com.
Whenever you type any domain name in the browser, it searches the IP address set for it such as 192.1xx.x.x, instead of communicating with the domain name. So whenever you type the domain name, it first converts to IP address and then opens on the internet.
The process of converting the domain name (hostnames) to IP address is called Domain Name Resolution. Although DNS is the advanced and most used way but there is another way too, to resolve the domain name, in which the Domain Name System (DNS) is not used and that is the “HOSTS File”.
Almost all the operating systems that communicate with TCP / IP keep the hosts file. This file is used to create mappings between domain names and IP addresses. HOSTS file is a text file that saves the entry of IP address and domain name. In this file, first its IP address and then after one space, its domain name comes in the same line. A lot of entries can be done in a hosts file.
