What is a Hosts File?

Before we dive into the specifics of the Windows Server 2012 R2 hosts file location, let’s first clarify what a hosts file is. In simple terms, a hosts file is a plain text file that is used to map hostnames to IP addresses. It’s essentially a local DNS resolution system that allows you to bypass the need for a DNS server when connecting to network resources.

Hosts files contain a list of IP addresses and hostnames that are used to resolve domain names to IP addresses. When you type in a URL, your computer will first check its hosts file to see if the domain name is listed there. If it is, your computer will use the IP address listed in the hosts file to connect to the website or server. If it’s not listed, your computer will then look to a DNS server to resolve the domain name.
