Let's try a real life example... lair bash[100] t www.cygnus.co.jp traceroute to godzilla.cygnus.co.jp (203.216.65.129), 30 hops max, 40 byte packets 4 bb1-fe0-0-100bt.rdc1.sfba.home.net (24.0.0.2) 22.423 ms 12.454 ms 5 bb2.mae-w.home.net (172.16.4.74) 16.154 ms 11.908 ms 6 mae-west.idc.ad.jp (198.32.136.117) 10.409 ms 13.88 ms 7 POS12-0-0.pat1.idc.ad.jp (158.205.224.74) 15.528 ms 22.436 ms 8 POS2-0-0.tok2.idc.ad.jp (158.205.224.69) 117.174 ms 117.271 ms 9 FastEthernet10-1.tok1.idc.ad.jp (158.205.224.129) 119.96 ms 117.687 ms 10 gol-tokyo.idc.ad.jp (158.205.226.66) 120.75 ms 119.334 ms 11 alpha-s4-0.gol.net (203.216.2.29) 133.704 ms 140.968 ms 12 oscar.bravo.gol.net (203.216.71.60) 137.724 ms 147.477 ms 13 lima3.gol.net (203.216.36.3) 144.454 ms 146.739 ms 14 tokyo-gw.cygnus.co.jp (203.216.65.190) 172.075 ms 165.382 ms 15 godzilla.cygnus.co.jp (203.216.65.129) 201.253 ms 168.145 ms No sprint, no uunet, no qwest, no backbone (well, technically idc.ad.jp appears to be backboning in jp land for gol.net), with MAE West in the middle. This is close to case 1. But dude, I'm in the Bay Area, and the other guy appears to be in jp. I didn't think we were in the same city. There is a special type of telcom circuit called a WAN circuit, it can go to a wide area, not limited to just the same city. Some people at MAE West actually have these special types of circuits called WAN circuits. Oh, and I thought 117 ms to get to .jp was neat in and of it itself. Last time I did this, it was at around 400 ms.
