These are Cloudamo NS used for all our services, we recommend using all 4 but you can go even with only 2 of them.
Just update your nameserver section on your current domain provider bellow with these NS and that is all.
ns1.server.plus
ns2.server.plus
ns3.server.plus
ns4.server.plus
NOTE: Please allow from 1 to 24 hours for DNS update, this will depend from your old provider.
