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 ***.***.***.***
