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.
So why not use m=65.0.0.0/6 ?
I can change my proposed syntax, and it would add at most 6bytes per
mech (.0.0.0) to require fully-specified IP quads.
