> Issue Type: Improvement
> Components: Core Framework, NiFi Registry

> Remaining Estimate: 0h
>
> Application bootstrap.conf configuration has included enabling
> {{java.net.preferIPv4Stack}} since NIFI-186.
> Although this setting can be changed, advances in IPv6 support across various
> libraries no longer require this as a default setting.
> The default preference for IPv4 should be removed from bootstrap.conf so that
> default Java settings will be applied. This setting should be removed for
> NiFi 2.0 to avoid impacting existing deployments, and new deployments of NiFi
> 2.0 can still add the setting if needed.
> The Java [Networking
> Properties|https://docs.oracle.com/javase/8/docs/api/java/net/doc-files/net-properties.html]
> documentation provides additional background on IPv4 and IPv6 preferences.
