Hi Nick,

That's good news! Do you know of any way to determine if 464XLAT/clat is active on the IOS12 device? With Android it was merely a matter of bringing up a shell with adb and looking for the clat interface but with IOS its not so simple unfortunately.

I am trying to determine under what conditions the clat is brought up on IOS12 for selfish reasons.

Regards
Kristian

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..
