IF THE DOMAIN IS REGISTERED WITH RX-NAME:
If you previously registered your domain on the RX-NAME.UA website and specified it when ordering your hosting package, it will automatically appear in your hosting control panel.

Please note that in this case, domain settings are configured in the hosting control panel, not in your personal account.

IF THE DOMAIN IS REGISTERED WITH ANOTHER REGISTRAR:
Set our DNS servers in your domain management panel:

ns1.rx-name.net  
ns2.rx-name.net  
ns3.rx-name.net

DNS changes may take effect within 1–48 hours.

If your hosting package allows adding more than one domain, you can add as many domains as you need in the hosting control panel.
