Cool idea, but why do we need any more syntax?  How is that
different from:
-ip4:64/6 -ip4:80.66/16 -ip4:192/3

Nevertheless, the original idea still stands.

AFAIK you can't skip the zeros in ip4.  So if what you have is
"very expensive 64/6, 80.66/16, and 192/3 stuff", and you want
a shortcut to exclude anything else at the begin, you could try

-ip4:0.0.0.0/2   from   0.0.0.0 up to  63.255.255.255
-ip4:68.0.0.0/6  from  68.0.0.0 up to  71.255.255.255
-ip4:72.0.0.0/5  from  72.0.0.0 up to  79.255.255.255
-ip4:80.0.0.0/4  from  80.0.0.0 up to  95.255.255.255
-ip4:96.0.0.0/3  from  96.0.0.0 up to 127.255.255.255
-ip4:128.0.0.0/1 from 128.0.0.0 up to 255.255.255.255

That's only for the 64/6 portion, I needed a quick script for
this "anticidr" task, and it doesn't handle more than one part.
