Re: .255 addresses still not usable after all these years?

I remember back in the day of old hardware and operating systems we'd intentionally avoid using .255 IP addresses for anything even when the netmask on our side would have made it fine, so I just thought I'd try it out for kicks today. From two of four ISP's it worked fine, from Verizon FIOS and Road Runner commercial, it didn't. So I guess that old problem still lingers?
The TCP/IP stack in Windows XP is broken in this regard, possibly in Vista as well, though I've yet to have the displeasure of finding out. I have a router with a .255 loopback IP on it. My Windows XP hosts cannot SSH to it. The specific error that Putty throws is "Network error: Cannot assign requested address".
At least if I ever need to completely protect a device from access by Windows users, I have a good option :)
