Hi Nick,

Congrats. The graph is beautiful. IPv6 going >20% in one month. Thanks for sharing.

BTW, could you confirm that Apple support for 464XLAT come out in iOS12? I may have missed it.
If a wifi device behind iOS device gets an IPv4 address (with or without IPv6 prefix), then 464XLAT must be working on it. Any datapoints would be superb !

Cheers,
Rajiv

Hi folks,
I want to mention iOS12 is driving our IPv6-only rollout.
Thanks to Apple make use of 464xlat for tethering (i..e. specific to wifi tethering interface to cellular), this has allowed us to skip dualstack on our common APN.
So I believe onboard apps just use Happy Eyeballs v2..
