A name service is central to the successful operation of your network. Without a functioning nameserver, your network may only display your computer's information.

There are many different name services in use. The Internet relies on the Domain Name System (DNS) protocol to translate IP addresses, such as 170.149.173.130 into nytimes.com.

With the HOSTS file, your system can perform a lookup on a listing of systems that are known, even if your automated name service fails.
