I am running Sierra (10.12.6) and am having problems with Internet connectinity that I believe may be caused by IPv6. Is thera way to disable IPv6 to force use of IPv4?
In network settings to Configure IPv6 I have no "Off" option, just "Automatically", "Manually" & "Link-local only". I have also tried "networksetup - setv6off Wi-Fi" through the command line but this didn't result in any changes from what I can see.
Thanks in advance for any help offered.

Yes I have seen your new thread also , as per this article :What is IPv6? - Apple Support
IPv6 offers other networking advantages. In most cases, computers and applications will detect and take advantage of IPv6-enabled networks and services without requiring any action from the user. IPv6 also relieves other networking issues that can arise due to the limited number of addresses available on IPv4. For example, IPv6 reduces the need for Network Address Translation, a service that allows multiple clients to share a single IP address, but is not always reliable.
To test your IPv6 connectivity, you can visit Test your IPv6.
You can click on test your IPV6 link , and whats the point of switching to IPV4 , you have to contact your servicer provider you must be using broad band connection .
Try link-local only. It will ONLY use IPv6 within your home, but not out on the internet.
If you really want to get your hands dirty, you can use an Applications -> Utilities -> Terminal session and the '/usr/sbin/networksetup' command with the -setv6off option
If you are using an Apple Airport Extreme BaseStation or Time Capsule, then Launchpad : Other : Airport Utility. Click the router image, choose Edit, and click the Internet tab on the Utility panel. Then click Internet Options... and set the Configure IPv6 to Link-local only. Click Update to apply the changes and reboot your router.
VikingOSX,
Thank you for your guidance. I am not using Airport or Time Capsule. I will start another thread as I have done some more investigation overnight and can now be a bit more precise (I hope).

Bob,
Thank you for your guidance. I tried both "link-local' and the command line apporach but neither improved my connectivity situation.
I will start another thread so that I can characterise my problem better.

Hello,
Thanks for your suggestion, which I did try but didn't seem to resolve my issue. Maybe I was implementing incorrectly.
I have posted another thread titled "No IPv4 Stack" that I believe is probably a more accurate representation of my issue.

Hello ! Chris .
You can read this article : macOS Sierra: Set up a 6to4 network port configuration
I guess I should have mentioned that I have a 4th gen Airport Extreme Base Station whose administrative interface may be different from more recent products.
The second screen shot I posted is by default , the method you wrote was correct , just enable the box of IPv6 sharing , click on save and finally on update .
Disable IPv6
