A parked domain is used to display the same website as a primary domain on WHM. If the domain you are adding as parked domain does not use your cPanel/WHM VPS as its nameservers, you may see the following error:
Sorry, the domain is already pointed to an IP address that does not appear to use DNS servers associated with this server.
You can resolve the issue in one of the following methods:
Go to WHM > Tweak Settings > Domains > Allow Remote Domains
Switch the option to On and click on Save.
Go to Main >> IP Functions >> Configure Remote Service IPs >> Remote DNS IPs
Add the IP addresses of the nameservers and click on save.
