This might be better on another list, since it's essentially a basic=20 networking question. The port net/ipcalc is quite useful for questions=20 like these as well. xxx.0.0.0/9 is the network xxx.0.0.0 through xxx.127.255.255 You can't get the exact range 1..100 without using multiple rules (or a s= et=20 of match patterns if you're using ipfw2).
