IPv6 Connection Feature - Operating Requirements for MacOSX

Here, you can check the recommended settings for an IPv6 connection, and how it will appear on your computer under normal operation.
The settings described here are the default settings on first startup of most computers, so you usually do not need to adjust settings. However, if you have trouble connecting with IPv6, please check each item has the appropriate setting.

The following explanation is based on macOS Sierra version.10.12.5.
