Bill, I see where I went wrong now that I went back and re-read your comment. I was conflating "longer" and "shorter". Thanks for your patience on this trying Friday.
Hi Jason, No sweat. Bit of an interesting history behind the terminology. We all used to say "larger" or "smaller" when talking about netmasks but that got confusing. Does larger mean more IP addresses (numerically smaller netmask) or does larger mean a numerically larger netmask (fewer IP addresses)? Some clever fellow (does anybody know who?) figured out that longer and shorter don't present that contextual confusion. There can be a longer netmask (more 1 bits in a row) but a "longer quantity of IP addresses" doesn't make sense.
