(5 word answer)I'm not sure if that's a typo or excessive evil on the part of the questioner. ;)My response would be: Discontiguous subnet masks were allowed in the pre-CIDR era.Yes, but even if it was *legal*, the "subnet doesn't contain 12 addresses" answer applies. ;)
It's just a mask...you can do all sorts of crazy things with netmasks. The results of using "unusual" ones is not typically predictable or desireable to those who might accidentally use them.
