If the application doesn't explicitly request IPv6, it doesn't get IPv6.
- wmf 9y agoAlmost all popular apps started requesting IPv6 before IPv6 was broadly deployed, so they weren't actually using it. Then when IPv6 was deployed, it was less reliable because stuff was untested and suddenly there was intermittent breakage everywhere. So apps had to be updated to use happy eyeballs.
- zAy0LfpBZLC8mAC 9y agoIf an app needs happy eyeballs, then that is because the IPv6 connectivity is broken, so you don't get to say that the app was not ready for IPv6.
