hardware address (i.e. MAC addresses). Certain

detect and eliminate loops in a network.

ARP Address Resolution Protocol. Computers on a LAN

use ARP to learn the hardware addresses (i.e. MAC

addresses) of other computers when they know only

their IP addresses.

IPV6 Multicast IP Multicasting under IP Protocol version 6. See IP
