I discovered this tool years ago and it's been very useful, but difficult to build on macOS. I filed an issue[0] that remains open.

Not sure if things have changed since then.

  Official Command Line Interface for the IPinfo API (IP geolocation and other types of IP data) (by ipinfo)

  

For another cli based IP address utility check out IPinfo.io's CLI: https://github.com/ipinfo/cli

It doesn't currently support calculations, but it does support conversion of start-end ranges to CIDRs (via `range2cidr` and `cidr2range`) and `grepip`. If you just want to get details for an IP it's gives a great overview, and supports bulk lookup too:

ipcalc is older than 2015, but it lived in a different repository:

https://github.com/fedora-sysv/initscripts/commits/313773794...

ipcalc gets removed here:

All in all it looks like ipcalc predates sipcalc by three years (1998 vs 2001)

  an ipv6 calculator built in rust that "looks and feel" like the ipcalc command on linux

shameless plug, I made an ipcalc6 in rust that does it (with colors)
