IPv4/IPv6 Subnet Calculator

SubNetCalc is an IPv4/IPv6 subnet address calculator. For given IPv4 or IPv6 address and netmask or prefix length, it calculates network address, broadcast address, maximum number of hosts and host address range. The output is colourized for better readability e.g. network part, host part. Also, it prints the addresses in binary format for better understandability.

Furthermore, it can identify the address type e.g. multicast, unique local, site local, etc. and extract additional information from the address e.g. type, scope, interface ID, etc.. Finally, it can generate IPv6 unique local prefixes.
