Could it be that you set the IP address manually some time ago? Check 
the file "/etc/network/interfaces". It should only have these entries:

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet dhcp

Or maybe additional entries similar to the last one if you have more 
than one interface. If there are manual settings, you could use the nm-
applet to change it to automatic DHCP connection. You should find the 
nm-applet in the top panel, the icon with two computers IIRC.
