Try using nslookup from a command prompt. Nslookup initially uses the default dns server you specified in your settings.
Here's an example session (some bits are in Italian, but this shouldn't be a problem):
C:\Documents and Settings\Administrator>nslookup
Server predefinito: www.routerlogin.com
Address: 192.168.0.1
> master.liveforspeed.net
Server: www.routerlogin.com
Address: 192.168.0.1
Risposta da un server non di fiducia:
Nome: liveforspeed.net
Address: 213.40.20.2
Aliases: master.liveforspeed.net
Then issue a server command with a dns of your choice (I use interbusiness dns servers in this test):
> server ns.interbusiness.it
Server predefinito: ns.interbusiness.it
Address: 151.99.125.1
> master.liveforspeed.net
Server: ns.interbusiness.it
Address: 151.99.125.1
Risposta da un server non di fiducia:
Nome: liveforspeed.net
Address: 213.40.20.2
Aliases: master.liveforspeed.net
What's the default dns server in your case? Does a different dns offer a different answer?
