If you would like to use VPSDime's DNS management service, you should use dns1.vpsdime.com and dns2.vcpsdime.com for nameservers.
To add your domain to our DNS management service, please login to your client area and go to the DNS Management page located at the top menu.
Alternatively, you can use your domain registrar's DNS service as most of them offer it free of charge.
