Ask your network administrator. :-)

I'm not sure there's any other way.  Perhaps you could watch all the 
routing traffic on your network (I don't know what the right filter 
would be for that, but you'd want to capture whatever routing protocols 
are being used on your network) and look at that traffic to figure out 
what gateways there are, or maybe you could get a table of the MAC 
addresses of all the machines on your Ethernet, and look for traffic 
sent to a MAC address with a destination routeable-protocol address 
(IPv4, IPv6, IPX, etc.) that doesn't correspond to the destination MAC 
address, which would probably imply that the MAC address was that of a 
router (but that wouldn't give you its routeable-protocol address - and 
there might be other reasons, e.g. proxy ARP or a mis-assigned routeable 
protocol address, why the packet might be sent to those addresses.
