This page contains all the Multicast IP Addresses and shows what protocol they are mapped to. Should you ever use a packet sniffer to try and see what’s on the network and you capture a packet with a destination IP Address of 224.X.X.X, then simply look up this list and you will know what the purpose of that packet was Internet Multicast Addressess Host Extensions for IP Multicasting [RFC1112] specifies the extensions required of a host implementation of the Internet Protocol (IP) to support multicasting. Current addresses are listed below. The range of addresses between 224.0.0.0 and 224.0.0.255, inclusive, is reserved for the use of routing protocols and other low-level topology discovery or maintenance protocols, such as gateway discovery and group membership reporting.
