IPv6 on Android devices.

[stevenlcroucher]

I know there are various issues with IPv6 on Android devices ranging from it being completely broken to laggy browsing and DNS issues. Is this likely to be fixed or is there a workaround?

My ISP offers IPv6 via dual stack which I enabled today on my Draytek 2860 router. All works fine on my Linux and Windows machines and I can see my Galaxy S5 (os v5) and Galaxy S4 (slightly older revision of os v5) both got IPv6 link and global addresses correctly, but were slow falling back to IPv4 as well as having all sorts of DNS resolution errors and routing problems. Even forcing it to use my Squid proxy was troublesome, and gave different issues. Oddly my Galaxy Tab 3 with 4.2.2 worked fine.

I've tried both DHCPv6 and SLAAC (with O-bit set) and both presented different issues. I tried to remove dynamic addressing from the LAN and even created a pure IPv4 vlan but the Galaxy handsets still got a link address from the router which screwed up internet access, so I've had to remove IPv6 entirely for the moment.

Are there any hacks to make it work or at least ignore v6 traffic? I'm surprised Google - one of the biggest pushers of IPv6 - can't get their handsets to support it properly.

Wikipedia says this: "IPv6 has been implemented on all major operating systems in use in commercial, business, and home consumer environments." But doesn't say anything specific concerning Android OS. Some ISP's and Web hosts have been slow to implement IPv6.

I remember reading about an issue with a Verizon LG G4 update that had an issue related to IPv6. I didn't get mine until after they fixed the problem, but others were talking about using an app called DNSet that worked in the mean time. Not sure if it'll help your problem, but with a look.
