If you're using DHCP, an IP address X is assigned to the card with MAC address Y and changing the MAC then renewing your lease is almost guaranteed to change your IP address. If the DHCP server is set to assign a static address to your computer, it does so by associating the static address with the MAC address.

Your ISP assigns it from their pool of available addresses. > On my tiny network, when someone plugs in a new computer, it just > assigns the lowest numbered unused IP address.

Yes, but while you have that address it IS associated with your MAC address. I think we're discussing two different OSI layers, though.
