Hmm..i'm sure i will catch hell for asking, but!:)

Having very little time to research on my own, i find it much easier, and
faster to just ask someone who already knows...

Just what is the /27, and the /32?

My first guess would be that it basically means all IPs between 32 and 27,
on the first one, 10 and 32 on the second...of course, that doesnt make
much sense..:)

Anyone up to giving me a brief (or long..) breakdown on this?

..david
