what's that smell?

Jason,

There're multiple answers depending on what you mean by "DNS server one
uses."

Whois on the domain will list the DNS servers of record. Some domains
also spread load over RNS servers so a dig, per a previous answer, will
give more specific announced servers currently in the zone files.

If you're using a current Windows box ipconfig /all at a command prompt
will show the actual DNS your machine is caching. There are similar *nix
commands but I'm not at home right now...

Best regards,

Hope this doesn't come across as DNS-101, but is there some way to tell
what DNS server one uses?  Kinda like telnetting to port 80 or 25?  I
know if it is possible, it's just as possible for them to change the
output, but chances are the brainiacs of the world who don't filter
probably aren't smart enough to change what their DNS server 'appears'
to be either.
