What is an AAAA-record? How do I create / change it?

As with the A-record, the AAAA-record (or the quad A record) links your domain name to an IP address. The difference is that the A-record works with IPv4 (eg 217.21.190.81) while the AAAA-record works with IPv6 (2002: 0: 0: 0: 0: 0: d915: be51).

Follow these steps in the control panel to set an AAAA-record: 

1. Go to “My products”> “DNS & forwarding management”> Click on the “DNS & forwarding” button to the right of your domain name.
2. Select “AAAA-records” in the menu on the left (see figure).
3. To change an existing AAAA-record , choose the host that you want to change and click on “Change”.
   Enter the new IP address and click on “Save”.
   Add a  new AAAA-record at the bottom of the list. Give a name to the subdomain in the left text field or leave it blank if you want to create the AAAA-record for the domain name itself.
   Enter the IP address 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/
