Network and IP Address Calculator

Displays the network, broadcast, first, and last usable IP addresses for a given network.

The subnet mask in "bit format" is also known as CIDR notation (CIDR = Classless Inter-Domain Routing).

IP Multicast Address Ranges

All multicast addresses can be easily recognized because they start with the bit pattern "1110".

224.0.0.0 - 224.0.0.255 are well-known multicast addresses for control channels.

224.0.1.0 - 238.255.255.255 are globally scoped (Internet-wide) multicast addresses.

239.0.0.0 - 239.255.255.255 are locally scoped multicast addresses.
