Examine the output of ifconfig:

gollum.deepsoft.com% cat /etc/sysconfig/network-scripts/ifcfg-eth0

Are you looking to find out your internal IP on the WAN/LAN, or your
external IP (what a site on the Internet would see you connecting
from)? Anyway, look at running ifconfig.

"/sbin/ifconfig" with any options is entirely sufficient; no "sudo || su" is
required.

"ifconfig" or "netstat -e -i" or look in the lease file of dhclient (or
whatever dhcp client software you use). RH/Fedora stores it in
/var/run/dhclient-<ifname>.lease. YMMV
