Can IP Addresses be Determined From MAC Addresses?
A MAC address represents the physical identifier of a network adapter, while the IP address represents a logical device address on Internet Protocol networks. A built-in feature of IP, Address Resolution Protocol (ARP) translates IP addresses to MAC addresses.
