.255 addresses still not usable after all these years?

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 :)
