ipcalc is completely different than the version used in Fedora

[Diftraku]

While trying to make a portable script that had few required binaries (ipcalc being one of them), I encountered a curious case where the Fedora version is completely different than the one distributed in Ubuntu.

This caused some issues as the behaviour is not consistent between the two (ipcalc on Ubuntu does not return 1 if it doesn't recognise the given input as a valid IP-address, where the one on Fedora does).

Ubuntu uses the ipcalc from http://jodies.de/ipcalc (https://launchpad.net/ubuntu/+source/ipcalc) where Fedora uses https://github.com/nmav/ipcalc (https://apps.fedoraproject.org/packages/ipcalc)

Would it be possible to harmonize the version used between the two or fix the behaviour to be similar to the Fedora one?
