Bug Description

Hi,

When running e.g.

    docker run --rm -it -p 80:80 traefik/whoami

this results in docker-proxy only listening on 0.0.0.0:80. And because of this

    curl -4 hostname

works, but

    curl -6 hostname

doesn't. It is meant to work, and this seems to be fixed in later docker versions:

https://github.com/moby/libnetwork/issues/2607

https://github.com/moby/moby/issues/42059

So, please get those fixes (20.10.6?) into ubuntu.

Thanks,
Paul

Some additional information from docker release notes:

docker.io 20.10.2 introduced a regression that disabled binding to ipv6 addresses: https://github.com/moby/moby/issues/41858

This regression was fixed in docker 20.10.6, see https://docs.docker.com/engine/release-notes/#20106 , fix is part of merged https://github.com/moby/moby/pull/42205

Please update docker.io in focal-updates to 20.10.6 to fix these regressions that impact many users using ipv6 with docker.io.
