IPv6 Subnet Calculator

The IPv6 Subnet Calculator performs network calculations on the given network address block, routing prefix and determines subnet address, host range and notation for the subnet.


There comes a time when a network becomes too large to manage and performance numbers hit the low as a result of too much traffic. One of the most effective technique to solve this network congestion problem is to break the TCP/IP network into smaller, more manageable pieces. The practice of dividing the network is called subnetting.
