Sipcalc is an advanced console-based IP subnet calculator. It can take multiple forms of input (IPv4/IPv6/interface/hostname) and output a multitude of information about a given subnet.
Features include:IPv4
- Retrieving of address information from interfaces.
- Classfull and CIDR output.
- Multiple address and netmask input and output formats (dotted quad, hex, number of bits).
- Output of broadcast address, network class, Cisco wildcard, hosts/range, network range.
- The ability to "split" a network based on a smaller netmask, now also with recursive runs on the generated subnets. (also IPv6)
IPv6
- Compressed and expanded input and output addresses.
- Standard IPv6 network output.
- v4 in v6 output.
- Reverse DNS address generation.
Robert W. suggests a pair of network administration tools and says:
Ever needed the proper netmask, in Cisco/decimal/whatever notation, at 3.50am, when you can't decide if you need to block 224.0.0.0/4 or /3?

Another package from Robert tomorrow.
I'm at OSCON this week in Portland, Oregon. Say howdy if you see me or come see me try avoid making a fool of myself at my presentation on Thursday afternoon.
More information on this package can be found on the Debian web site.
