1] What Is a Hosts File in Windows PC

A Hosts file is a local file that maps domain names and their corresponding IP addresses. The operating system uses it to resolve domain names to their corresponding IP addresses when a user tries to access a website. It is present in all major operating systems and is a map for locating and recognizing IP hosts.

When you visit a website, your computer checks the Hosts file to see which IP address it connects to. If the data is missing, your internet service provider will search the DNS for the necessary resources to load the website.

2] Why Modify a Host File in Windows?

The HOSTS file can be edited to block access to specific websites by mapping their domain names to a non-existent IP address or to redirect traffic from one domain to another by mapping the domain name to a different IP address.

It’s an excellent tool that has its advantages and drawbacks, so make sure when you are editing it you know what you want to achieve.

The Hosts file is composed entirely of plain text. As a result, you can update it using any text editor, such as Notepad, for instance. Remember, though, that the changes will impact only the system where the Hosts file is located.

3] Where Is a Hosts File Located?

Each operating system has a unique host file location. Given below is the location of the Hosts file on a Windows 10 or 11 PC:

 Local Disk (C:) > Windows > System32 > drivers > etc > hosts
