This is called the Zeroconf network ... it happens automatically in many
OSes (Windows since win98, Mac, many Linuxes) and is designed to make
the machine reachable on a network even with a botched network setup.

You can make it go away with this entry in /etc/sysconfig/network: 

NOZEROCONF=yes

Then restart the network service ... "service network restart" (or
reboot the machine)

However, this does remove some functionality.  For more info about
zeroconf and what it can do see:

and

-------------

If your network is properly configured, you should be able to turn off
Zeroconf with no problems.
