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

contain information on ports, addresses, priorities,
and costs, and are exchanged across bridges to
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
