Can the "/##" an address spec be any sized mask? /22 ? /20 ?
Try it. ;) Works for me.
Also, I noticed that nmap will scan the net address and broadcast
address themselves. Should it not be coded to not scan these?
If you're doing 126.96.36.199/24, then you can avoid net/broadcast by using
Admittingly, it would be cool to have a switch to bypass broadcast/net
addresses, but that's extra calculation to figure out (what's the
broadcast/net of the nmap input address of 188.8.131.52-8?)
