nslookup

Default Server: UnKnown
Address: 10.20.1.1
>
Leaving you at a prompt within nslookup. Here you will be able to see the Default Server name which reflects your DNS server name and Address which reflects your DNS server IP address.
In here, you can type in any hostname for which you would like to get the IP address.

nslookup wikipedia.org
