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.

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