Hello Geeky, so today we are focusing on How To Turn-on IPv6 in MacOS. So please read this tutorial carefully so you may comprehend it in a better helpful way.

Guide: How To Turn-on IPv6 in MacOS

Each Internet connection has a unique digit address known as an Internet Protocol (IP) address. Currently, most IP addresses use the standard 32-bit IPv4 standard, but IPv4 addresses run faster. The solution is to use longer IP addresses, which is exactly what IPv6 does. Using 128-bit web addresses, IPv6 generated around 340 billion addresses. What should we continue for a while!

IPv6 is the next generation of Internet transport protocol. Most Internet traffic today uses IPv4. However, IPv6 internet traffic is growing rapidly and will eventually overcome IPv4. All key components of the university network infrastructure support both IPv4 and IPv6 traffic The following instructions how to activate and enable IPv6 on PCs running the latest versions of Windows, macOS, and Red Hat Linux.

Enable IPv6

In Apple macOS (all versions), OS X (all versions), and Mac OS X (versions 10.3 Panther and later), Internet Protocol version 6 (IPv6) is turned on by default. There are no necessary steps to enable IPv6. It also supports versions of Mac OS X 10.0 Cheetah, 10.1 Puma, and 10.2 Jaguar but comes off by default.

In the absence of practical policy or guidance about hard to be careful against IPv6-related attacks, a guide for configuration Apple macOS (all versions) is provided by this thing and OS X (versions 10.10 Yosemite and 10.11 El Capitan) are provided by this thing. For macOS (all versions), OS X (all versions), and Mac OS X (version 10.6 Snow Leopard), follow these instructions to activate IPV6 manually.

If the following features has worked, advising them to be disabled as shown here:

  • File sharing in OS X (all versions) and Mac OS X (all versions) and
  • AirDrop in OS X (all versions) and Mac OS X (all versions),

Re-enable IPv6

To re-enable IPv6 in macOS (all versions) and OS X (version 10.8 Mountain Lion and later) if disabled for some reason, use the command line

  • networksetup -setv6 automatic Wi-Fi

(and re-command line again for Ethernet and other network interfaces you want to re-enable IPv6 on). Once IPv6 is activated for a view, you can then use the Settings Options – Network panel as described in the next paragraph to manually add your address settings. To re-enable IPv6 in OS X (version 10.7 Lion) and Mac OS X (all versions), open Settings Preferences – Network panel. Go into the properties for each network view and click on Advanced – TCP / IP tab. Then click Configure IPv6 button and set the menu to On. Click OK and then Apply Now. Pa System.

If you insist on using the command line, the command to turn on IPv6 for all network interfaces is

  • / usr / sbin / ip6 -a

Storage addresses are disabled by default in OS X (version 10.7 Lion) and Mac OS X (all versions). Since then they have worked by default in macOS (all versions) and OS X (versions 10.8 Mountain Lion and later). To disable their use with sysctl (which must be activated whenever the program restarts):

  • sysctl –w net.inet6.ip6.use_tempaddr = 0

while removing them completely, place these in /etc/sysctl.conf

  • net.inet6.ip6.use_tempaddr = 0

or, if that variable has already been defined change its value to zero. Next, restart the program. To re-enable them for a while after they are completely disabled, use sysctl:

  • sysctl –w net.inet6.ip6.use_tempaddr = 1

and to specify how many times the address has been recalculated (XX is in seconds), use sysctl.

  • sysctl -w net.inet6.ip6.temppltime = XX

To reactivate them completely, change the net.inet6.ip6.use_tempaddr value in /etc/sysctl.conf to 1, or add the following lines to /etc/sysctl.conf (XX is in seconds):

  • net.inet6.ip6.use_tempaddr = 1
  • net.inet6.ip6.temppltime = XX

and restart the program.
