Summary of results/responses from my posting re: what the hell gives
with subnet masks greater than 8 bits ( on a Class A or B net ID ) ?
 
The answer, briefly, is: nothing gives.  Provided there are at least
two bits for the host IDs, you can do anything ya want.  There were
numerous caveats about which particular subnet schemes would be supported
by routing hardware; for example, non-contiguous bitmasks aren't always
supported, and neither are mixed-field-length subnets.

I'd like to thank everybody who took the time to respond to my posting, and
for the high quality, as well, of the responses.  Low BS to content ratio.
