How to Edit File Host – A Complete Guide

Host files predate the Domain Name System and can still be found in popular operating systems such as Windows and macOS. They are an effective way to address the same issues as a DNS. But how can you edit a hosts file and locate it?


For answers to these questions, keep reading. In this blog, you will find a comprehensive guide on how to edit a hosts file. You will learn what a hosts file is, what it does, and whether you should edit it or not.

What is a Hosts File?

The hosts file works similarly to a DNS. It is a directory that stores the IP addresses of various websites. When you visit a website, your computer will first check the IP address in the hosts file and match it with the relevant hostname.


But if the IP address is not found in the hosts file, the computer will then turn to the DNS to look up the website's IP address based on its hostname. The hosts file is present in most operating systems.

Should You Edit a Hosts File?

Editing a hosts file is generally considered safe, as it's a simple text file that can be opened and modified using any basic text editor.


The most common reason for editing a hosts file is to change a website's domain name. When moving your website from one hosting provider to another, your site may be temporarily unavailable while the domain name propagates, which can take up to 48 hours.


However, by modifying the hosts file on your computer, you can access your website immediately using the new domain name
