Dear All,

Does anyone have any experience debugging IPv6 on Android devices? Are there tools and docs?

My phone and tablet sometimes use IPv6, sometimes they won't, and I find no obvious way to monitor and influence this process.

I generally use http://test-ipv6.com/ to see if a device is using IPv6 or not, and sometimes it is and sometimes it is not.

On the wire (actually WiFi), I see Router Advertisements from my FreeBSD router, but sometimes no Router Solicitations from the Android devices, which means their IPv6 support has stopped working again.

My mobile connection is IPv4 only.
But when I am connected with WiFi at home it will consistently have dual stack.

Sorry ... no clue what could cause your behaviour.

I have native mobile ipv6. I have used 'ipv6 and more' app to check the address. Not much debugging.. ;)

Do you mean "Mobile IPv6" or IPv6 on your mobile?

I wrote my thesis on "Mobile IPv6" (now RFC 6275 - Mobility Support in IPv6 - IETF Tools) that is why I am asking ;)

Mine too.

But when I am connected with WiFi at home it will consistently have
dual stack.

My phone can also be dual stack (it shows both the IPv4 and the IPv6 addresses in the network properties, and the IPv6 address is the correct public address from my home WiFi network), but http://test-ipv6.com/ in the Chrome browser shows that IPv6 is not available. Sometimes it shows that IPv6 is available but
is not preferred.

Any ideas would be appreciated.

A nice app btw, thank you. But even if the app shows that IPv6 addresses are present on the phone's interfaces, the browser still does not use it.

Both, I guess. ;)

My telephone operator provides native ipv6 address to my phone.

For my it always shows proper dualstack.

Mobile IPv6 is an additional protocol.

IPv6 is one protocol.
"Mobile IPv6" is an extension of it.
99.99999% of IPv6 nodes do NOT support Mobile IPv6.
So if you do not know what I am talking about you have IPv6 without the mobility option.
As I assumed ;)

After a software update on the phone, a miracle happened: https://drive.google.com/open?id=0B6fElyRl5MUDRGM0X2dVdGpwS0E

The only thing I don't understand is why the test says "SLAAC=no" while in fact
it *is* SLAAC (I don't have any DHCPv6 server on this network, just a rtadvd).

OTOH, "after" does not always mean "in consequence of."
