Operation Manual – MulticastH3C S3100 Series Ethernet Switches Chapter 1 Multicast Overview1-8Table 1-2 Range and description of Class D IP addressesClass D address range Description224.0.0.0 to 224.0.0.255Reserved multicast addresses (IP addressesfor permanent multicast groups). The IPaddress 224.0.0.0 is reserved. Other IPaddresses can be used by routing protocols.224.0.1.0 to 231.255.255.255233.0.0.0 to 238.255.255.255Available any-source multicast (ASM)multicast addresses (IP addresses fortemporary groups). They are valid for theentire network.232.0.0.0 to 232.255.255.255 Available source-specific multicast (SSM)multicast group addresses.239.0.0.0 to 239.255.255.255 Administratively scoped multicast addresses,which are for specific local use only.As specified by IANA, the IP addresses ranging from 224.0.0.0 to 224.0.0.255 arereserved for network protocols on local networks.
