Hi,

This morning (Thurs) I tried to tracert "nf" and got the following results
from Win98

 C:\>tracert nf

  Tracing route to nf [203.12.249.101]
  over a maximum of 30 hops:

   1   227 ms   228 ms   238 ms  star.st.net.au [203.37.129.5]
   2   210 ms   208 ms   198 ms  gw-ti2.st.com.au [203.37.222.2]

  Trace complete.

Notice line 8 - "read-rfc1918-for-details.iana.net".  I don't see how
rfc1918 allows for this
Private IP Address to be used for routing purposes.
