- 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.
