To calculate an IP address select the IP version, introduce an IP address, choose a bitmask/prefix length and click "calculate".
In addition to the standard subnet calculator functions it can also be helpful in configuring IPv6 reverse DNS delegation as well as it can be used as IP address converter. It accepts the following IP address formats as input: dot-decimal notation (IPv4), colon-hexadecimal notation (IPv6), binary, integer, hexadecimal.
The subnet calculator includes an advanced IPv6 addressing plan builder which permits to create organization specific hierarchical IPv6 address allocation schemes. Read more...
