One way that probably works on many *nix systems is to look something up 
with nslookup or dig command, which will tell you which nameservers it 
querried. There is probably a more elegant way, but it seems to work:

twiggy:~> nslookup www.google.com
Server:  dns.atl1.speakeasy.net
Address:  216.27.175.2

Non-authoritative answer:
Name:    www.google.akadns.net
Addresses:  64.233.161.104, 64.233.161.99
Aliases:  www.google.com

twiggy:~> dig www.google.com

; <<>> DiG 8.3 <<>> www.google.com
