> To enable dualstack and IPv6 support, we use
>  InetAddress.getAllByName(hostname) to resolve the IP addresses of a host.
> When the system property java.net.preferIPv4Stack is set to true, only IPv4 addresses are returned and any IPv6 addresses are ignored, so no extra check is needed to exclude IPv6.
> When java.net.preferIPv4Stack is false, both IPv4 and IPv6 addresses may be returned, and any IPv6 addresses will also be added as connectors.
> To disable IPv4, you need OS level configuration.
