可以确定，我确实是正确配置了 docker 的 IPv6 环境。但是 redroid 似乎不支持 IPv6 接入。

[zhouziyang]

Only ipv4 configs are added in redroid currently. Well, you can manually add ipv6 network configs (address, route etc.). I'm not sure any command to specify ipv6 dns.

[zhouziyang]

BTW, why ipv6 is required here?

Because it is simple. Just make it become a server without NAPT. And i have IPv6-Only web site. I need to make it to be "IPv6 reachable".

I was trying to switch the container networking type from "bridge" to "host". Then i found the fact - Android is not support DHCPv6 but SLACC only. It was finally obtain an IPv6 address and ruin mine host network as cost.

[zhouziyang]

Should not use host network mode, otherwise your host networking might be messed up.\

Take a look at https://github.com/remote-android/vendor_redroid/blob/8b2ad82cd7fa0fb1db927542b44c9c84594e93b9/ipconfigstore/main.cc and https://android.googlesource.com/platform/frameworks/base/+/93edcc139722cc6c3f8dc3368846ae364d8ae82d/services/core/java/com/android/server/net/IpConfigStore.java I think it's feasible to add ipv6 support.
