Names! A-NAMES, C-NAMES, & Sub-Domains


There are many different ways to set up name servers for your website, and many different terms that may need some explanation. These three terms pop up often – be sure to be familiar.

A-NAME – This is your website’s address record. An A-NAME is where the IP address of your main server is set, as well any other sub domains that need to point to other servers via IP address.

C-NAME – Similar to an A-NAME, a C-NAME points to a different server and redirects to the new location.

Sub-Domain – A sub domain is a domain that uses a prefix before your registered domain (sub.domain.com). These domains can sometimes be used to point your domain to another part of your website, or another server all together.

Using A-NAME, C-NAME, and sub-domains can be a very effective way to implement new software, test new builds of your website, or direct web traffic to other locations. It is recommended that you follow any available documentation, or contact the technical lead on your project before adjusting existing name server settings.
