why would you want to dusable broadcast scans, that gives you valuable info like what routing protocol they use, if they use ntp etc. same goes for the subnets, you want to scan for them since this will tell you what address to spoof in case of router's access lists.

later.

I have a class B net, chopped up into variously sized subnets. Can the "/##"
an address spec be any sized mask? /22 ? /20 ?

Also, I noticed that nmap will scan the net address and broadcast address
themselves. Should it not be coded to not scan these? Or perhaps a more
flexible language for specifying address such as "x.x.x.x/xx EXCEPT x.x.x.x
..." ?
