Hi Daniel - it looks like your changeset is reverting all the changes that were made by [JDK-8046500](https://bugs.openjdk.java.net/browse/JDK-8046500), to fix an issue where no interfaces were returned on machines that had only IPv6 interfaces (and no IPv4). See https://mail.openjdk.java.net/pipermail/net-dev/2018-November/011931.html ; 

Were you able to test that `NetworkInterface.getNetworkInterfaces()` will not fail on a machine where IPv4 has been disabled with `netsh interface ipv4 uninstall` ?
