On CPanel 11.30+ when you go to “Main >> DNS Functions >> Nameserver IPs” and found that the nameservers listed is wrong (this might happen if you just finished doing server migration), you can fix it by following these steps:
1. Make sure that you already update the child nameservers to the new IPs and its fully propagated.
2. Go to “Main >> Server Configuration >> Basic cPanel & WHM Setup” and click on “Assign IP address” button on each of your nameservers. Make sure that the IP being shown on the pop-up window are the correct IP for your nameserver.
3. Login to your server as root and run the script: /usr/local/cpanel/scripts/updatenameserverips to update CPanel nameservers list.
4. Check “Main >> DNS Functions >> Nameserver IPs” again and it should show the correct settings.
