for routing info,
# route
[root@cap1tnairn-w1 ~]# route
Kernel IP routing table

or

# ip route
[root@cap1tnairn-w1 ~]# ip route
10.117.80.0/22 dev eth0  proto kernel  scope link  src 10.117.80.40
169.254.0.0/16 dev eth0  scope link
default via 10.117.80.1 dev eth0
[root@cap1tnairn-w1 ~]#
see the src part... that sets my from address which is assigned..

also check

ip addr
[root@cap1tnairn-w1 ~]# ip addr

       valid_lft forever preferred_lft forever
2: eth0: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast qlen 1000
