I have Windows 10 PRO installed and IPv6. I don't get any temporary IPv6 addresses. I only get a Link Local and the Global Unicast address from the DHCP.

'Use Temporary Addresses' are enabled and also 'randomize identifiers' are also enabled. See the output.

How do I get my Windows machine to generate and use IPv6 Temporary addresses?

    Hi there,

    I suggest you to try this CMD to enable it and see how it goes

    Open an Elevated Command Prompt.

    a). Enter the following command to enable the random IP address generation feature and then press enter:

    netsh interface ipv6 set global randomizeidentifiers=enabled

    Then input the next command to allow Windows to randomly generate a temporary address to use for network communication.

    netsh interface ipv6 set privacy state=enabled

    Restart your PC and check if their are any temporary ID created

    Hope this Answers all your queries , if not please do repost back .

    @Limitless Technology Unfortunately still no temp IPv6 after successfully executed your command.

    But all my other machine (Windows and Linux) also lack a temp ipv6 address. What is responsible for the temp addresses? Is it the router or the host?

    I'm using a Unifi Dream Machine Pro router.

    p.s. sorry for my late response, I didn't got a notification of your post.
