Wouldn't they both be equivalent to 192.168.0.4, for example?
No, the ip address or the nnn.nnn.nnn.nnn as you called it is a software assigned address. The xx:xx:xx:xx:xx:xx address is hardcoded into the nic and each nic has a unique one. This is called a mac address. A dhcp server will read the mac address and use this to reserve a specific ip address for a machine throughout the lease period, but they are not related in any way. -- /g
