Traceroute is not actually connecting. Try getting IE (or any other browser)
to connect to a host with an address like that. The packets never leave the
source. We had to change a customer implementation because Macs and other
sensible OS could connect but Windows XP hosts (many of them - all running
SP3) could not.

And if you read the Microsoft technote about it, they will tell you it
doesn't work for everything XP SP3 and earlier and it is fixed in Vista.
