What is DNS (Domain Name Services)

Learn more about Domain Name Services (DNS) and how it translates domain names into IP addresses.
DNS functions as the Internet's "yellow pages." Each web server, email server, etc. has an IP address (Internet Protocol address) that is unique to that server. Trying to remember the IP address of your favorite web sites would be impossible, so DNS was created.
DNS is the Internet service that translates domain names (e.g. yahoo.com) into IP addresses. Because domain names are alphabetic, they're easier to remember. The Internet, however, is really based on the IP address. Every time you use a domain name, therefore, a DNS service must translate the name into the corresponding IP address. For example, the domain name www.example.com might translate to 18.104.22.168.
When you type in a web site, such as Coxbusiness.com, your browser connects to a DNS server on the internet. Your browser asks for the IP address of the web site Coxbusiness.com. Once the IP is obtained, a request is made to the web server for the page you requested.
