Sipcalc is an console based ip subnet calculator with IPv4 and IPv6 support.

Sipcalc development started back in 2001 and has most of the features I want in an ip calculator. It is no longer under active development, though bugfixes and patches are accepted.

Sipcalc is available in many Linux/BSD distributions, usually as a package named sipcalc. Release tarballs are available from http://www.routemeister.net/
