I have been working quite a lot with IPv6 lately trying to get a few large cloud deployments into dualstack configuration. I have also been working on IPv6 only networks and ran into a couple of strange behaviours.
My test setup includes a segregated network with no ipv4 config on it but full ipv6.
This is attached to both wired and wireless network.
My macbook appears to be coping well, same for ipad and iOS in general.
But I cannot get Android to work.
Connecting to a wlan with no ipv4 assignment marks the network as inaccessible. That’s despite correct Ipv6 config. I also noticed that android seems to default to ipv4 when in dualstack, which is opposite to iOS.
Is this vendor specific or is it android in general?
Any info appreciated
