Private networks and home.{net|com}

[shrdlu () PACBELL NET (Etaoin Shrdlu)]

So we're looking for a little odd something, and we do a simple traceroute,
and what do we see? What the heck are those IP addresses at hops 15, 20, and
21? I thought that those weren't supposed to be passed, and there are three
of them in one traceroute. This kind of destroys the meaning of the concept
of a "private network," especially if insane numbers like these are going to
show up in routing tables. Am I just not understanding something here?
