If you know what the IP address of your computer is, you can use the "dig" or "nslookup" command from a shell prompt on your desktop or Dante or Homer to see if you already have a DNS name.

To learn more about requesting a domain name or an IP address please go to our IP request page. If you are obtaining an IP address automatically with DHCP server, the DHCP server will assign a DNS name. Computers using DHCP cannot be assigned a custom DNS name.
