How would PC1 figure out R3’s Unicast MAC Address for the first time? Note: Unicast Address is the mostly used Media Access Control Address among network devices. It is a 12-digit Hexadecimal with most of the time carries the following value, this is an official (IANA) Multicast address. To a specific group – Frames sent using Multicast Ethernet address will be copied and forwarded to a subset of devices on the LAN that volunteers to receive such frames which sent to a specific multicast address – for specific group only and NOT to everyone. Meaning to everyone – Frames sent using this address should be delivered, received, and processed by all devices on the Ethernet LAN or VLAN.īroadcast conclude 12-digit Hexadecimal address with value of inserted into the destination filed of the Frame. So the IEEE defines categories of group addresses for Ethernet communications: A frame sent to a group of addresses might be delivered to a small set of devices on the LAN, or even to all devices (everyone) on the LAN. Group addresses identify more than one LAN interface card. In addition to unicast addresses, Ethernet also uses group addresses. Every MAC address represent a single NIC in the world hence, it is called Unicast (Unique) Global Address.
