How To Turn-on IPv6 in MacOS – Guide
Each Internet connection has a unique numeric address known as an Internet Protocol (IP) address. Currently, most IP addresses use the older 32-bit IPv4 standard, but IPv4 addresses are rapidly depleting. The solution is to just use longer IP addresses, which is exactly what IPv6 does. Using 128-bit web addresses, IPv6 generates about 340 billion billion addresses. Which should keep us going for a while!
IPv6 is the next generation of the Internet transport protocol. Most Internet traffic today uses IPv4. However, IPv6 Internet traffic is growing rapidly and will eventually replace IPv4. All major components of the university’s network infrastructure support both IPv4 and IPv6 traffic. These instructions explain how to enable and disable IPv6 on PCs running the latest versions of Windows, macOS and Red Hat Linux.
Enabling IPv6
On Apple macOS (all versions), OS X (all versions), and Mac OS X (versions 10.3 Panther and later), Internet Protocol version 6 (IPv6) is enabled by default. No action is required to enable IPv6. It was also compatible with Mac OS X 10.0 Cheetah, 10.1 Puma, and 10.2 Jaguar versions of Mac OS X, but was disabled by default.
In the absence of an applicable policy or guidance on how to protect against potential IPv6-related attacks, the guide to configure Apple macOS (all versions) is provided by this article and OS X (versions 10.10 Yosemite and 10.11 El Capitan) is provided by this article. For macOS (all versions), OS X (all versions), and Mac OS X (version 10.6 Snow Leopard), follow these instructions to manually enable IPv6.
If the following features are enabled, it is recommended that they be disabled as shown here:
Reactivating IPv6
To re-enable IPv6 on macOS (all versions) and OS X (version 10.8 Mountain Lion and later) if it has been disabled for some reason, use the command line
(and reissue the command line for Ethernet and any other network interfaces on which you want to re-enable IPv6). Once IPv6 is re-enabled for an interface, you can use the System Preferences – Network panel as described in the next paragraph to manually assign its address settings. To re-enable IPv6 on OS X (version 10.7 Lion) and Mac OS X (all versions), open the System Preferences – Network panel. Access the properties of each network interface and click on the Advanced – TCP / IP tab. Then click Configure IPv6 button and set the menu to On. Click OK and Apply Now. Close the system.
If you insist on using the command line, the command to enable IPv6 for all network interfaces is
Privacy addresses have been disabled by default in OS X (version 10.7 Lion) and Mac OS X (all versions). Since then, they have been enabled by default on macOS (all versions) and OS X (versions 10.8 Mountain Lion and later). To disable its use with a sysctl (which must be run every time the system is restarted):
while to disable them permanently, put the following in /etc/sysctl.conf
or, if this variable is already defined, change its value to zero. Then restart the system. To temporarily reactivate their use after they have been permanently disabled, use sysctl:
and to specify how often the address is recomputed (XX is in seconds), use sysctl
To permanently re-enable them, change the value of net.inet6.ip6.use_tempaddr in /etc/sysctl.conf to 1 or put the following lines in /etc/sysctl.conf (XX is in seconds):
and restart the system.
