This could be a good topic for presenting to the WG. Want to volunteer to write up a document and/or presentation on the state of IPv6 deployment in the root and TLD name servers, routing anomalies, etc, etc? It would be good to hear someone's first-hand experiences with this stuff: what went wrong, how it was worked around or solved, what could be done better, future directions.

Check http://www.sixxs.net/misc/latency/ and select the "IPv6 between POPs and well known destinations" option to reveal some ugglyness. I've been monitoring most of them for quite some time already and I also did some testing with the IPv6 only test root's (see http://www.rs.net) The POPs mentioned btw are the located all over Europe at various independent ISP's add .sixxs.net to find out exactly where or see the POP page on the site. Average latency to b.root-servers.net at least 294ms. H.root-servers.net was gone for sunday to monday and so on.... Not even minding the packetloss. E and I are also there btw, though that is not on the root-servers.org site.

Personally, I don't see why you care about the RTT to a root server. A well-behaved name server will make 4-5 queries to a root server once a week or so.

<SNIP> That is indeed true, but it is rather odd when a machine is physically close and good connectivity between for instance Amsterdam and Sweden exists and then one still has traffic going over the US... But this is more a problem of the state of the IPv6 routing tables and the fact that only I is in europe and is only even testing IPv6 connectivity. Thus a presentation or better a debate about how the IPv6 routing can be improved in general would be a better subject and prolly the place for that is the ipv6-wg. But as people know who go there Gert Doering has been doing those updates for quite some time already and last time at least there was some discussion about the MIPP draft. Even as it has improved considerably in the last couple of years we are not there yet.. Greets, Jeroen
