Why Edit Your Hosts File?

Updating the hosts file on your computer is useful for development purposes. You can preview how your site will look on another server without affecting the live site that users view.

It is particularly useful when creating a development site for WordPress since it uses absolute urls. Creating the development site on a new server with the same domain means that you will not have to complete a database find and replace query when you’re ready to move the new site live.

In order to update the host your domain loads from, you will need to know the IP address for the new server you want to preview.
