why did you make this choice? is there a known bug with ipv6? I think
it
would be useful to put an option in the wireguard application, so that
we can choose.
Seems like the origin of this behavior is this[1] commit that cites
issues with DNS64. I've CC'ed Jason who originally wrote the commit and
should have better insight into it.
if I want to use an ipv6 tunnel, do I have another solution than to
create 2 tunels, one in ipv6 only, and another in ipv4 in order to be
able to use ipv6 when available and ipv4 when the place where i am has
no ipv6?
I believe that's the way as of now, yes.
I did not manage to add 2 endpoint in a single tunnel to put an
endpoint
only ipv6 and another endpoint ipv4 / ipv6 to bypass the problem
thanks,

hello,
I've always encountered a bug with android wireguard when using an
ipv4
/ ipv6 endpoint.
I tested with two phones:
Huawei p10 lite android 8.0 emui 8
Xiaomi poco m3 android 10.0 miui 12
When i'm in LTE (not yet been able to test in wifi), wireguard
connects
to the endpoint in ipv4 and not in ipv6, and i don't understand why
it
is doing that.
The WireGuard Android client is designed to prefer IPv4 over IPv6 as
of now
(https://git.zx2c4.com/wireguard-android/tree/tunnel/src/main/java/com/wireguard/config/InetEndpoint.java#n97).
This may or may not change in the future, and we'll announce here if
it does.
However, chrome, for example, does use ipv6 by default and not ipv4.
My phone does recover an ipv6 in 2a01: cb1a ........ / 64 and not an
ipv6 type fc00 / fd00 / fe80 ...
I also specify that if I only have an AAAA record, the tunnel works
fine
in ipv6. but suddenly, I can no longer connect to wifi which only
have ipv4.
I would like wireguard to favor ipv6 when it is available, and
otherwise
switch to ipv4.
Is it possible ?
Thanks,
Jerem

Harsh
