In the Internet addressing architecture, the Internet Engineering Task Force (IETF) and the Internet Assigned Numbers Authority (IANA) have reserved various Internet Protocol (IP) addresses for special purposes.
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. It uses specially reserved multicast address blocks in IPv4 and IPv6.
In computer networking, multicast is a type of group communication where data transmission is addressed to a group of destination computers simultaneously. [1] Multicast can be one-to-many or many-to-many distribution. [2] [3] Multicast differs from physical layer point-to-multipoint communication.
Sent by multicast routers to determine which multicast addresses are of interest to systems attached to the network(s) they serve to refresh the group membership state for all systems on its network. Group-specific membership queries Used for determining the reception state for a particular multicast address. Group-and-source-specific queries
Some large / 8 blocks of IPv4 addresses, the former Class A network blocks, are assigned in whole to single organizations or related groups of organizations, either by the Internet Corporation for Assigned Names and Numbers (ICANN), through the Internet Assigned Numbers Authority (IANA), or a regional Internet registry.
The Internet Engineering Task Force (IETF) and IANA have restricted from general use various reserved IP addresses for special purposes. [4] Notably these addresses are used for multicast traffic and to provide addressing space for unrestricted uses on private networks.
According to RFC 3171, addresses 224.0.0.0 to 239.255.255.255 are designated as multicast addresses. Routers take care of making copies of datagrams and sending them to all receivers that have registered their interest in receiving targeted data. Anycast: Like broadcast and multicast, anycast is a one-to-many routing topology. However, the data ...
