|Typically ifconfig doesn't show the default gateway address. At least, not on my OpenBSD boxes or any of the linux boxes I've played with.|
curtr@cs5:/usr/home/curtr> ifconfig em0
em0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
media: Ethernet autoselect (100baseTX full-duplex)
inet xxx.xxx.4.57 netmask 0xffffff00 broadcast xxx.xxx.4.255
inet6 fe80::211:2fff:fe74:7b61%em0 prefixlen 64 scopeid 0x1
If you have a Mac, look for the Network Settings in the GUI and check in there to find out your DG. If you know your way around BSD (OS X is BSD based after all), you could check in the /etc folder and see if there's a mygate file. If there is, that will contain the DG address as well.
curtr@cs5:/usr/home/curtr> cat /etc/mygate
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
