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
docs.example.com. When someone visits
documents.example.com they will see the exact same content as
Add a CNAME record
To use CNAME records, select CNAME from the Add Record drop down in the advanced editor. Then enter the hostname you would like to alias from and the fully-qualified domain name you would like to alias to. You may also enter
@ in the Alias for field to represent the domain itself.
For example, if the domain were
example.com and you wanted
www.example.com to point to
example.com you could put
www in the name field and
@ in the alias for field.
