Description
Umbrella bug to track various point improvements in IPv6 Support. This issue can track both implementation improvements and additional API and/or spec updates.

Some possible additional API points:

1) For retrieving an InetAddress instance representing either the IPv4 and IPv6 loopback address, regardless of the -Djava.net.preferIPV6Address property.

2) For performing either IPv4-only or IPv6-only name service lookup, rather than shuffling through getAllByName or being dependent on the -Djava.net.preferIPV6Address property.

3) Improve address selection for network clients

4) ...
