There is a longstanding bug in Windows TCP/IP stack which prevents it
from communicating properly with hosts whose final octet is .0 or .255.

The bug was fixed in Vista, but there are a lot of old Windows XP
clients out there.

If you are using these IP's only for internal communications then I
don't see a problem, but if you expect Windows clients elsewhere on the
network to be able to talk to these IP's, you will run into problems.
