An IPv6 capable ipcalc replacement written in Go.
I wrote this to get an equivalent breakdown of ip space from
ipcalc but with IPv6 support.
After writing this I learned that ipcalc does in fact support IPv6, but with a different argument syntax and throws CIDR parsing error/warning messages onto the screen.
Not too horrible to deal with, but I'll keep using this version since it now exists.
This version is functional, but missing a few bits of polish that I have planned still.
