Output will look like this:

eth0      Link encap:Ethernet  HWaddr 00:0D:B9:13:14:38
          inet addr:192.168.24.99  Bcast:192.168.24.0  Mask:255.255.255.0
          UP BROADCAST MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b)
          Interrupt:10 Base address:0x1000

lo        Link encap:Local Loopback
          inet addr:127.0.0.1  Mask:255.0.0.0
          UP LOOPBACK RUNNING  MTU:16436  Metric:1
          RX packets:294 errors:0 dropped:0 overruns:0 frame:0
          TX packets:294 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0
          RX bytes:30124 (29.4 Kb)  TX bytes:30124 (29.4 Kb)


Note that this machine does not have it's WiFi enabled. This machine's
IP address is 192.168.24.99 (eth0). You could get fancy by using
regular expressions (egrep) but that might seem a bit scary for the
uninitiated.


Hmm, odd that machine appears to have broken counters, oh well I'll
fix that later.
