You're confusing IP address with Ethernet address.  Each Ethernet
network interface comes pre-configured with its own unique Ethernet
address in the world.  That's the number on the sticker.  Normally
there's no need to change it, but most boards allow changing the
Ethernet address via software.

The IP address is a higher level address for TCP/IP (level 3 of the
protocol stack) that is usually configured into software.  A protocol
named ARP (Address Resolution Protocol) is used to map between IP
and Ethernet addresses.

Hope that answers your question.
