Arthur, Several tests require the presence of either: 1) IPv4, or 2) IPv6, or 3) IPv4&IPv6. A test library utility class could provide such.
Here is a rough idea about how to determine Internet Protocol support. http://cr.openjdk.java.net/~chegar/8220673/webrev.00/ It might be enough to experiment with and see how far it gets us? -Chris. P.S. Let's use the `[ipv6]` subject prefix to track related work in this area.
