Which address is a multicast address?

The multicast addresses are in the range 224.0. 0.0 through 239.255. 255.255.

What is a multicast address used for?

An IP multicast group address is used by sources and the receivers to send and receive multicast messages. Sources use the group address as the IP destination address in their data packets. Receivers use this group address to inform the network that they are interested in receiving packets sent to that group.

How do I find a multicast address?

Multicast addresses are identified by the pattern “1110” in the first four bits, which corresponds to a first octet of 224 to 239. So, the full range of multicast addresses is from 224.0. 0.0 to 239.255. 255.255.

What are 224 IP addresses?

224.0. 0.22 is a multicast-address. Multicast is thought for ip addresses which can be “subscribed” to. A multicast IP can be subscribed to by multiple network interfaces and will be routed by routers in a special way.

Can I ping a multicast address?

You can only ping, via multicast, hosts which are subscribed to the multicast group which you are pinging. You need to be careful about which multicast groups you use, and, in general, you should use multicast groups from the administratively scoped range of 239.0.

Which address is a multicast MAC address?

The multicast MAC address is a special value that begins with 01-00-5E in hexadecimal. The remaining portion of the multicast MAC address is created by converting the lower 23 bits of the IP multicast group address into 6 hexadecimal characters.

What is multicasting IP address?

The IP address that defines a multicast group is a Class D address (224.0. 0.0 to 239.255. 255.255). A computer uses Internet Group Management Protocol (IGMP) to report its multicast group memberships to multicast routers.

How many multicast addresses are there?

RFC 3180, superseding RFC 2770, envisioned the use of the range for many-to-many multicast applications. Unfortunately, with only 256 multicast addresses available to each autonomous system, GLOP is not adequate for large-scale broadcasters.
