The A and AAAA records (and more important: the services) will stay even after that day. It’s just a good starting point for us – and we plan to have all services up and running with IPv4 and IPv6 support from now on.

As we are an open source community, we are in the lucky position to be able to fix possible IPv6 software issues on our own. Some might need more time to be fixed – but over all we want to have the infrastructure and our packages up and running with IPv6 constantly.

Plenty of sites do. The only downside is that there are a few users on the Internet whose computers think they have IPv6 when they really don’t (typically due to a network configuration, like someone trying to configure IPv6 but giving up). This means that when that person tries to visit a site with an A and AAAA, they will need to time out on IPv6 before it falls back to IPv4.

Recent studies/testing have put this brokenness rate somewhere around 0.3% or lower. Personally, I have been running a significant number of sites and services (DNS, mail, etc) with A+AAAA for years and have not yet encountered a user who was facing issues.

The article/news item above fails to explain this, but it is the only real reason why large companies have been hesitant to put AAAA records live on their site. Hopefully IPv6 day will allow them to test this, show them that it is a non-issue, and then after analyzing their findings they will put an AAAA back on for good.

Is there a downside if they just leave their AAAA lookup working after this? Isc.org does.

Ha ha, I support Ryan point of view.

hm, is OpenSUSE planning on turning on AAAAs just for that day, or potentially leaving them up afterwards too? It says “on that day” but I don’t see a particularly strong indication whether it will be only for that day or from that day forward.
