What is a CNAME-record? How do I create / change it?

A Canonical Name Record or CNAME-record is a type of DNS-record that links an alias name to a real, or canonical, domain name.

CNAME-records are usually used to link a subdomain, such as “www” or “mail”, to the domain in which the content of that subdomain is hosted.
The most famous example of a CNAME-record is the redirect from www.mydomain.com to mydomain.com. This way the website can be called up in two ways, with and without www. before.

 

Follow these steps in the control panel to set a CNAME-record:

  1. Go to “My products”> “DNS & forwarding management”> Click on the “DNS & forwarding” button to the right of your domain name.
  2. Select “CNAME-records” in the menu on the left.
  3. To change an  existing CNAME-record , choose the host that you want to change and click on “Change”.
    Enter the new destination and click “Save”.
    Add a new CNAME-record at the bottom of the list. Enter the subdomain in the left text field without the main domain (see example below).
    Enter the destination and click on “Add”.
  4. The changes are activated. Remember that this can take 1 to 4 hours. You can check the active records via:  http://who.is/dns/ CNAME-records

Tip: You can always leave the TTL value at the default value of 3600.

Changes to your CNAME records will only take effect after 1 to 4 hours

The distribution time is usually 1 hour, but can go up to 4.
