Someones being naughty again...

Sat Mar 14 01:29:38 UTC 1998

I don't see a problem here ?

According to RFC 1918 the Net 10 and Net 172.16/12 and 192.168/16 addresses are
for use privately or internally such as when :
"   - Interfaces of routers on an internal network usually do not
      need to be directly accessible from outside the enterprise."

These addresses are however not advertised to the outside world and should thus
cause no problem here.

We are simply seeing those net 10 addresses as a source address for those
packets returned by the traceroute, but that address should not be reacheable
or advertised from outside the internal network.

See http://www.cis.ohio-state.edu/htbin/rfc/rfc1918.html for more details.
