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

Google has a daft idea that they should not properly support IPv6, but only do it they way they think it should work.  So Android does do IPv6 with SLAAC addresses, but if you set up your network like I have done mine with DHCPv6 only, then Android devices will not get a unicast IPv6 address.  They will work with link-local addresses.  Many businesses require DHCPv6 in order to control the addresses assigned on their networks and this Android problem creates them many difficulties.  So if you are using DHCPv6, you will need to allow SLAAC as well, or root all your Android devices and install the available root-only DHCPv6 app.

You do have to wonder – if even Microsoft can't get IPv6-only working, what chance is there for any other company to?





My first ever network connection was a 1MHz AM crystal(OA91) radio receiver.
