1. What is DNS?

Domain Name Servers (DNS) translate domain names or records created by users into numerical IP addresses used by computers. For example when you type in appriver.com it translates to the IP address (67.192.226.174) of our web server. Once translated it takes you to our website.

An analogy for DNS is that it serves as a phone book for the Internet. When a user wants to visit your website or send you an email your computer uses DNS records to determine where to send the data.
