+      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. Also,
+      it prints the addresses in binary format for better understandability.
+      Furthermore, it prints useful information on specific address types (e.g.
+      type, scope, interface ID, etc.).
