A multicast address is a logical identifier for a group of hosts in a computer network that are available to process datagrams or ... IP multicast address range ...
IP multicast is a method of sending Internet Protocol (IP) datagrams to a group of interested receivers in a single transmission. It is the IP-specific form of multicast and is used for streaming media and other network applications.
In IP multicast the implementation of the multicast concept occurs at the IP routing level, where routers create optimal distribution paths for datagrams sent to a multicast destination address. Multicast is often employed in Internet Protocol (IP) applications of streaming media , such as IPTV and multipoint videoconferencing .
Multicast is the most common approach, and each VXLAN network identifier (VNI) is mapped to a single multicast group, while each multicast group may map to one or more VNIs. When a VTEP comes alive it uses the Internet Group Management Protocol to join the multicast groups for the VNIs it uses. When a VTEP has to send BUM traffic it will send ...

Group Address: 32 bits This is the multicast address being queried when sending a Group-Specific or Group-and-Source-Specific Query. The field is zeroed when sending a General Query. The message is sent to the following IP multicast addresses: [8]: §9
IP multicast also describe IP multicast software (i.e. VideoLAN,qpimd – PIM Daemon for Quagga, GNU — PIM module for the Quagga Routing Suite, UFTP, etc.). The multicast routing is specific and broad range of protocols for layer-3 routing protocol for multicast feature and it is defined in RFC 5110. [5]
In SSM, an IP datagram is transmitted by a source S to an SSM destination address G, and receivers can receive this datagram by subscribing to channel (S,G). See informational RFC 3569. PIM-SM is commonly used in IPTV systems for routing multicast streams between VLANs, subnets or local area networks. [5]
