169.254.0.0/16 is the auto-configure range. And it's not just MS Stuff,
it's actually RFC'd (RFC3330)

http://www.faqs.org/rfcs/rfc3330.html

   169.254.0.0/16 - This is the "link local" block. It is allocated for
   communication between hosts on a single link. Hosts obtain these
   addresses by auto-configuration, such as when a DHCP server may not
   be found.

If 127.0.0.1 isn't a loopback ... then what is answering for it when I ping it - and all I have plugged into my NIC is a looped RJ45?
