Assunto: Weird trace route output


Has anyone seen a Class C private Address when running a trace route
outside of their own network or domain?

Notice the 15th hop address.
Some stuff has been *** for my protection ;-)

Tracing route to ***.com [216.159.234.11]
over a maximum of 30 hops:

  1    <1 ms    <1 ms    <1 ms  ***.***.***.***
  2    <1 ms    <1 ms    <1 ms  ***.***.***.***
  3     1 ms     1 ms     2 ms  ***.***.*** [**.***.***.***]
