Where did they got version 1 from? It is not on the official site:

http://jodies.de/ipcalc-archive/

Could you look at the package information to see if they mention another 
URL, please?

Could be <https://github.com/nmav/ipcalc>, but they mention version 
0.2.3... Ah, it is <https://gitlab.com/ipcalc/ipcalc>, that's 1.0.0
