Hehehehe... Only when having bad dreams!
That always strikes me as one of those "last day" kinda things!

I always thought it would be cool to have a mask like 255.255.255.1. Then
you would have all the odd addresses on one subnet and the even addresses on
another. :-) I've heard that the standards don't actually forbid this. (That
may be a networker's urban legend, I haven't personally checked it out.) But
even if the standards permit no one implements these non-contiguous masks
because of the reasons y'all have stated. It'd be fun though wouldn't it?

Fortunately, for everyone's else's brain cells and the programmers
hairlines, you weren't on the committee to come up with the concepts of
subnetting! (smirk)
Mathematically, it will work, however it's a REALLY bad idea, and the router
knows this. ;)

Scott,
In my opinion it logically works. It is much more difficult for us non-CPU
units to decipher; and I think it would kill supernetting as we know it.
