IPv6 Addressing - Multicast Addressing
What is Multicast Addressing?
Multicast addressing is a method where data is sent from one source to multiple specific receivers in a group, using a single transmission.
Why is Multicast Addressing useful?
It reduces network load by allowing efficient delivery of data to multiple recipients without sending multiple copies of the same data stream.
How it works?
Devices join a multicast group using protocols like IGMP (for IPv4) or MLD (for IPv6). The sender transmits data to a multicast IP address, and routers forward the packets only to networks with group members.
Where is Multicast Addressing used?
It is used in IPTV, video conferencing, live streaming, online gaming, and routing protocols like OSPF, EIGRP, and RIPng.
Which OSI layer does this protocol belong to?
Multicast addressing operates at the Network Layer (Layer 3), though group management also involves the Data Link Layer and Application Layer in some contexts.
Is Multicast Addressing Windows specific?
No, multicast addressing is not Windows specific. It is supported by all major operating systems including Windows, Linux, and macOS.
Is Multicast Addressing Linux specific?
No, multicast addressing is not Linux specific. It is widely supported across all network-capable operating systems.
Which Transport Protocol is used by Multicast Addressing?
Multicast is typically used with UDP, as it is connectionless and suitable for one-to-many transmission. TCP does not support multicast.
Which Port is used by Multicast Addressing?
Ports depend on the application. For example, routing protocols like OSPF use port 89, while others like streaming may use dynamic or well-known UDP ports.
Is Multicast Addressing using client-server model?
Not strictly. Multicast typically follows a one-to-many model rather than a traditional client-server model.
