Windows 10 1809 Edge not loading pages

I have done a ton of testing on this. The problem was affecting about 100 computers across four different businesses, and therefore four different active directories, and four different networks. First off I have to excoriate Microsoft for even making IPv6 a requirement on Edge because 100% of our ~89 customer networks cannot even use IPv6. Their ISP does not have IPv6 at all and cannot allocate addresses. I called Spectrum today. Not only do they not provide an IPv6 prefix (space) to a customer, but they won't even take it as a feature request. Nope.

So that means you cannot actually even obtain internet routable base for your IPv6 space to configure inside your network.

Then if you consider the fact that most perimeter security appliances won't NAT IPv6 to IPv4 or vice versa, then they will just dump any IPv6 traffic that is headed to the internet. I know this to be true as I tested it. Check this out even after you have an IPv6 address.

So if your ISP won't give you an IPv6 space, and your equipment is going to dump IPv6 traffic anyway, then why how and when will it ever be used? I don't see any purpose or value for IPv6 on the inside of a LAN. We have NAT. I don't want all devices on the LAN to be directly inbound routable from the WAN without going through security inspection at a security appliance. So I see IPv6 where your endpoints have WAN addressable IP addresses as a security risk.

But you say that a private space could be used. https://simpledns.com/private-ipv6

Sure of course. But again, what is the point? The traffic will never leave the network to get to the internet.

So Microsoft loves to turn themselves into a swear word by claiming that IPv4 is deprecated as of 2011 and then forcing this change on us when it is technically impossible to even properly configure IPv6 for most networks.

I'm going to give you a set of commands that may or may not solve your problem if you are having it. First verify you don't have a GPO that is disabling IPv6. If you do, set the GPO to Enable all IPv6 components. Any other option will not work. Reboot computer and verify that HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters" /v DisabledComponents is zero.

Then do this:

Get-NetAdapterBinding -ComponentID ms_tcpip6

Look for anything that has a value other than true. If so, do this:

Enable-NetAdapterBinding -Name "*" -ComponentID ms_tcpip6

Reboot.

If you are still not getting IPv6 autoconfiguration address, then do this:
