Is there a way to look past the local dns server (192.168.1.1) and see where it is getting its information from?

The situation is this: I am at work and see that my dns server is 192.168.1.1, when I perform a query for www.google.com it comes back as 192.168.1.1


Monsi:~ monsi$ nslookup
> server
Default server: 192.168.1.1
Address: 192.168.1.1#53
Default server: 4.2.2.1
Address: 4.2.2.1#53
> www.google.com
Server: 192.168.1.1
Address: 192.168.1.1#53

Non-authoritative answer:
www.google.com canonical name = www.l.google.com.
Name: www.l.google.com
Address: 74.125.224.147
Name: www.l.google.com
Address: 74.125.224.148
Name: www.l.google.com
Address: 74.125.224.144
Name: www.l.google.com
Address: 74.125.224.145
Name: www.l.google.com
Address: 74.125.224.146

However, I know it is simply a local address pointing to an outside dns server. I would like to know what dns server my company is using without having to ask them (they don't trust me :P ).

Anyone have any ideas? Anyone know if this is even possible?
