What is a CNAME record?

CNAME stands for Canonical Name. CNAME records can be used to alias one name to another.

For example, if you have a server where you keep all of your documents online, it might normally be accessed through docs.example.com. You may also want to access it through documents.example.com. One way to make this possible is to add a CNAME record that points documents.example.com to docs.example.com. When someone visits documents.example.comthey will see the exact same content as docs.example.com.
