A hosts file is a plain text file that maps your hostnames to Internet Protocol (IP) addresses. Whenever Windows connects over a network using a hostname, it refers to the hosts file. Why do you want to Change your Hosts File? Changing your hosts file is a temporary measure to preview your site as it will load from your Verpex server using the preview link ( https://sitepreview.org/). You can make changes on a server other than the one loaded by your domain using a hosts file while visitors visit your webpage. It allows you to test how your website looks on a different server when your DNS has not propagated. You can also use the hosts file to control access to certain websites or network traffic. Your host file might have been edited maliciously in an attack, this is known as a hosts file hijack.
