Re: Where does your 6to4 relay address (192.88.99.1) go?
Primus Business DSL in Toronto..

From what it seems like:

| I am quite certain that your traceroute in fact did get to its destination. 6to4 relay routers, per rfc, don't use 192.88.99.1 as source address for a reply. 192.88.99.1 is just an anycast address to reach the nearest relay. If you look at the PTR record that was retrieved for the last hop,
15 ipv6gw00-cc1.rm-com.net (217.173.143.232) 141.839 ms 146.873 ms *
You will see that it claims to be an IPv6 gateway of some sort. It's real (non-anycast) IPv4 address is 217.173.143.232. I can't say that it actually works, because I haven't tried it myself, but I would say two out of three of your test packets on the final hop did reach their destination. |

| That's exactly the same router I get sent to, in fact. I used to have an IPv6 tunnel (freenet6) that went to Europe a few years ago, and it wasn't so bad, since Europe's rather ahead of N. America in IPv6 deployment anyways, and you might be going there anyways much of the time.
The real downside to a European tunnel is connectivity to Japan. (Lots of good IPv6 sites in Japan -- they're way ahead of the pack.) I don't think Europe and Asia have that good Internet connectivity with each other in general. Your v6 packets will come back from Europe over the Atlantic, cross the U.S., and head out from California to cross the Pacific before they go to Japan, if I remember correctly. You might get a whole second of latency by the time you add your tunnel in.
I don't know why Europe Asia traffic routes through the U.S. I think maybe the Internet started from the U.S. Gov't and fanned out from there, and maybe the NSA likes to slurp up what comes through. China will soon (and may already) be starting to route more of that traffic away from America, though.
Might be worth a shot, anyways, if just to map out the v6 world from France. |
