Bug fixes and enhancements

• Native Windows containers are configured with an internal DNS server for container name resolution, and external DNS servers for other lookups. Not all resolvers, including nslookup, fall back to the external resolvers when they get a SERVFAIL answer from the internal server. So, the internal DNS server can now be configured to forward requests to the external resolvers, by setting "features": {"windows-dns-proxy": true } in the daemon.json file. moby/moby#47584

Note

This will be the new default behavior in Docker Engine 27.0.

Warning

The windows-dns-proxy feature flag will be removed in a future release.
