Disable IPv6
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.
