   This document uses the term "routable address" to refer to all
   unicast IPv4 addresses outside the 169.254/16 prefix, including

   This document uses the term "routable address" to refer to all valid
   unicast IPv4 addresses outside the 169.254/16 prefix that may be
   forwarded via routers. This includes all global IP addresses and
   private addresses such as Net 10/8 [RFC1918], but not loopback
   addresses such as 127.0.0.1
