Only Ipv6 support for Docker


We have a requirement to use Ipv6 only Internal network. As part of that, we need to make docker to use Ipv6 only.
Could you please let me know if it is possible to enable only Ipv6 in Docker and avoid docker from assigning Ipv4 addresses?
When i tried, it is creating a default Ipv4 in 172 subnet which i do not want.
Also for the ports exposed on host, docker is trying to redirect from Ipv6 to a Ipv4 address from host.
If you have any thread where this ws already discussed, please point me to that link.
