DNS records added via the "DNS Manager" section in the Control panel take effect only when the domain name uses the DNS service of your hosting account.
In order to apply changes to your DNS records, you need to:
1. Log into your Control panel and navigate to the "DNS manager" section.
2. You can apply the changes globally for all domain names parked on the hosting account, or for a particular domain name only. Select the appropriate option from the "Select a domain" -> "Apply changes for" drop-down menu.
3. At the bottom of the page you will see an "Add a new record" field. Select "AAAA" from the "Type" drop-down menu.
4. Enter the name in the "Subdomain" field. If you need to point www.example.com to another IP address, then you need to type www in the "Subdomain" field. In the "IP" field type the IP address of the server to which you want to point the AAAA record.
After applying all values, click on the "Submit" button.
