- mortehu 10y agoIf you can't access IPv6 enabled sites, you can't access Google, Facebook, Wikipedia, or Netflix, who all enabled IPv6 permanently in 2012[1]. According to [2], around a third of US has IPv6 connectivity. If AAAA records constitute some big problem, it's not well known. 1. http://www.worldipv6launch.org/participants/?q=1 http://www.worldipv6launch.org/participants/?q=1 2. https://www.google.com/intl/en/ipv6/statistics.html#tab=per-country-ipv6-adoption&tab=per-country-ipv6-adoption https://www.google.com/intl/en/ipv6/statistics.html#tab=per-...
- throwaway2048 10y agoThats not how it works, if you only have IPv4, AAAA records have no effect. Google et all continue to work via IPv4.
- mortehu 10y agoI'm not sure what you're referring to when you say "Thats not how it works". I was referring to people with broken IPv6 setups, mostly Teredo and 6to4 (old Mac OS X versions), for whom IPv4 worked but IPv6 was not actually routable. At the time, publishing AAAA records would lock out all of those users.
- mirashii 10y ago> If you can't access IPv6 enabled sites, you can't access Google He was referring to your lack of qualification in the above. An IPv4 user can indeed access Google, which is an IPv6 enabled site.
- mortehu 10y agoOh, I see now. You're reading "Having IPv6 access is a necessary for accessing Google". What I meant was "If the presence of AAAA records means you can't access a site, then you can't access Google". A user who only has IPv4 connectivity relies on their software recognizing this when accessing an IPv6 enabled site. Software's failure to do so is one of the main reasons for the slow rollout of IPv6.
