IP address, how to find

[heidi]

(I'll be a newbie for ever.  Thanks for help at last fall's InstallFest.)
How do I find my own computer's ip address.  If I type ifconfig I get 
the standard:

inet addr:192.168.0.101  Bcast:192.168.0.255  Mask:255.255.255.0

Someone wants to look into the Red Hat Linux 9 I have installed on my 
computer to help me troublshoot.  This is a pieced together computer 
with an ethernet connection.

Thanks,
