Windows 10: How to force Windows to use ULA as valid IPv6 Internet

I know ULA is not meant for Routable to Internet, but I have multiple subnet to partition Family, Guest, HomeLab and IoT Device. Thus making other LAN subnet to have IPv6 Internet.however Telekom Malaysia refuse to provide customer at-least /60 prefix:so I end up with /64:Telekom Malaysia use RA for Router IPv6 Address and Routable LAN via DHCPv6But Windows refuse to use ULA as valid NAT66, thus all apps will revert back to IPv4 despite IPv6 NAT66 ULA -> GUA is workingI have properly setup DNS Server at fccd::10 AdGuard and fccd::11 PiHoleI have properly setup NAT66 on Mikrotik RB5009

Windows 10 with IPv6 ULA and NAT thinks it's not connected to the IPv6 Internet

My little LAN is connected to two ISPs and I internally run ULAs so I can make explicit client-to-ISP assignments by centrally NATing my clients onto the respective ISP prefix.

All Windows applications from ping to Edge can access the IPv6 internet without any issues. Nevertheless, probably thanks to the ULA, Windows 10 reports "no IPv6 internet access" upon checking the status of the LAN interface.

There must be some method that this part of the Windows OS uses to decide whether it has a routable IPv6 internet address or not. I already tried to play with the prefixpolicies table in netsh.exe, but to no avail, mainly because I'm having a hard time understanding the incredibly scarce documentation.

Is there some setting anywhere (netsh.exe, registry, where else?) where I can add an ULA range so all parts of Windows 10 recognize they do have working IPv6 internet access despite ULAs being in use?

 

World IPv6 Launch Solidifies Global Support for New Internet Protocol

Major Internet service providers (ISPs), home networking equipment manufacturers, and web companies around the world are coming together to permanently enable IPv6 for their products and services by 6 June 2012.

Organized by the Internet Society, and building on the successful one-day World IPv6 Day event held on 8 June 2011, World IPv6 Launch represents a major milestone in the global deployment of IPv6. As the successor to the current Internet Protocol, IPv4, IPv6 is critical to the Internet’s continued growth as a platform for innovation and economic development.





“The fact that leading companies across several industries are making significant commitments to participate in World IPv6 Launch is yet another indication that IPv6 is no longer a lab experiment; it's here and is an important next step in the Internet’s evolution,” commented Leslie Daigle, the Internet Society’s Chief Internet Technology Officer. “And, as there are more IPv6 services, it becomes increasingly important for companies to accelerate their own deployment plans.”

ISPs participating in World IPv6 Launch will enable IPv6 for enough users so that at least 1% of their wireline residential subscribers who visit participating websites will do so using IPv6 by 6 June 2012. These ISPs have committed that IPv6 will be available automatically as the normal course of business for a significant portion of their subscribers. Committed ISPs are:

• AT&T
• Comcast
• Free Telecom
• Internode
• KDDI
• Time Warner Cable
• XS4ALL

Participating home networking equipment manufacturers will enable IPv6 by default through the range of their home router products by 6 June 2012. Committed equipment manufacturers are:

• Cisco
• D-Link

Web companies participating in World IPv6 Launch will enable IPv6 on their main websites permanently beginning 6 June 2012. Inaugural participants are:

• Facebook
• Google
• Microsoft Bing
• Yahoo!

Content delivery network providers Akamai and Limelight will be enabling their customers to join this list of participating websites by enabling IPv6 throughout their infrastructure.
As IPv4 addresses become increasingly scarce, every segment of the industry must act quickly to accelerate full IPv6 adoption or risk increased costs and limited functionality online for Internet users everywhere. World IPv6 Launch participants are leading the way in this effort.

About the need for IPv6
IPv4 has approximately four billion IP addresses (the sequence of numbers assigned to each Internet-connected device). The explosion in the number of people, devices, and web services on the Internet means that IPv4 is running out of space. IPv6, the next-generation Internet protocol which provides more than 340 trillion, trillion, trillion addresses, will connect the billions of people not connected today and will help ensure the Internet can continue its current growth rate indefinitely.

About the Internet Society
The Internet Society is the world’s trusted independent source of leadership for Internet policy, technology standards and future development. Based on its principled vision and substantial technological foundation, the Internet Society works with its members and Chapters around the world to promote the continued evolution and growth of the open Internet through dialog among companies, governments, and other organizations around the world.
