Nice! I have two follow-up questions: (1) Some DNS servers have added AAAA for their servers. If they run slave servers for some TLD's, those TLD's "suddenly" have AAAA records for one of their nameservers. Maybe these cases are the real world "experiments" we should look closely at? Have we heard any complaints? I am especially thinking of ns.ripe.net which have one A and one AAAA record. (2) In Sweden we are discussing adding AAAA to the zone, and have also made some studies (not run by me, I am a passive participant in the practical tests). We have tested things like possible problems resolver libraries have to send queries to a nameserver IF the nameserver have both A and AAAA records, the resolver have Ipv6 enabled, but not IPv6 connectivity to the nameserver. Will the resolver fall back to IPv4 transport? It should, and what we have found so far is that it does. I hope we can have some data before the next RIPE meeting. Has anyone else looked at potential problems like this? paf On 2003-10-20, at 15.28, Ronald van der Pol wrote:
At RIPE 46 we presented measurements about the effects of adding IPv6 glue to the root zone.
As promised, we made more measurements and have written a document: http://www.nlnetlabs.nl/ipv6/publications/v6rootglue.pdf
