You can find that out on Windows from the command prompt with 'nslookup'


On Linux systems you can use 'nslookup', 'dig' or 'host' to find it.

Here is an example on Linux:
$ nslookup hotvoip.com
Server: 10.16.36.29
Address: 10.16.36.29#53

Non-authoritative answer:
Name: hotvoip.com
Address: 77.72.174.52

$ dig hotvoip.com

; <<>> DiG 9.9.2-rl.028.23-P2-RedHat-9.9.2-10.P2.fc18 <<>> hotvoip.com
