Hmm, well the first packet is a TTL exceeded message.  Do you suppose
the RFCs call for a high TTL for that specific message, since one would
want to be sure it doesn't also die due to TTL issues?  This is just
speculation, but it would make sense...  The max TTL is of course 255,
so maybe that box is 25 hops away?
