Unicast Multicast And Broadcast Addresses Study Ccna Pdf This tutorial explains unicast, multicast, and broadcast in detail. learn three address types used in a computer network through examples. I'm very new to computer networking and i'm trying to figure out this dilemma about the unicast, multicast and broadcast transmissions. i was told that mac address are unique for each device and they don't change.
Multicast Mac Address Difference Between Multicast Broadcast And This article describes the different ethernet address types, which are unicast, multicast, and broadcast addresses. The three principal “cast” methods unicast, broadcast, and multicast are defining in the field of computer networks. these all are useful for different factors and can be used for one to one, one to many or many to many transmissions. The source mac must always be a unicast mac address of the network card that sent the frame. it would be totally illogical to see a broadcast multicast mac address written in the source mac field. Cast is a packet that's sent to all devices on specific network. the de tination address in the packet is the special broadcast address. if the packet has a broadcas address, all devices that receive that message will process it. so, a l devices on the same network segment will see the same message. another th.

Class d address used for multicast ranges from 224.0.0.0 to 239.255.255.255 these addresses used as destination addresses, not source addresses. a packet sent to a multicast group always has a unicast source address. The unicast address has the mac address of the target device. multicast frames have a value of 1 in the low order bit of the first octet of the destination address. That said, network interfaces will ignore the frames that do not have their mac address or a broadcast address. (unless you want to hear it in promiscuous or monitor mode).
