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 :)

We had to split our assigned ranges (PPP/PPPoE) into /24, even if it
were assigned to the (NAS, BRAS, etc) in larger chunks. It seems
customers who were assigned the .0/.255 could get out there - but
certain sites (IIS it seemed) would refuse to talk back.
I forget if I tested microsoft.com like this...
