This is not necessarily wrong, I used to have a dialup account where connections within the UK would go often go to London, then go round a tour of Western Europe, and then come back through London.

I think Point-to-Point links just work like that, with arbitrary addresses on either end of the link. My address and gateway have only the first byte in common. > [/usr/home/andy] > -> traceroute -n 67.41.38.201 > traceroute to 67.41.38.201 (67.41.38.201), 64 hops max, 52 byte > packets 1 * * * > 2 67.41.38.201 40.303 ms * 39.421 ms > > Why on earth would there be delays on the first hop when not using > name resolution? I don't see what name resolution has to do with the delay, the 39ms is the round-trip time to the gateway at the ISP.
