while in earth package.

Adding the domain using addon tools it through following the error message.

Error from park wrapper: Using nameservers with the following IPs: 98.124.192.1,98.124.193.1,98.124.196.1,98.124.197.1,69.64.145.225 Sorry, the domain is already pointed to an IP address that does not appear to use DNS servers associated with this server. Please transfer the domain to this servers nameservers or have your administrator add one of its nameservers to /etc/ips.remotedns and make the proper A entries on that remote nameserver

Solution for that problem

So first you need to update the proper name server for the client domain name for which one you want to add domain

Then allow 24 to 72 Hours then try it.
