At the lowest level, they are completely unrelated. In a practical
sense, methods exist for assigning IP addresses based on MAC
addresses, but your ISP almost certainly has assigned your IP address
to your physical line, and changing your MAC address is unlikely to
have any effect on your IP address.

Changing your MAC address is as easy as buying another ethernet card
and substituting it. For a PC, that makes it pretty trivial. For a
router, it's as simple as buying another router. But neither of these
will have any detectable effect outside your local net.
