• Why does address change

    From Joe Delahaye@1:249/303 to All on Fri Sep 2 13:41:06 2016
    Having re-installed windows twice now from the original setup, I have a different IPv6 address with each installation. I have used the Netsh commands to disable tunnel, teredo, etc, and the mac address has not changed. I asked this before, but, it is quite possible that any answer may have become lost due to the problems I was having. It seems stable again now. I am not certain though (without restarting system again) if the address changes with each reboot. Here is what I have so far. From the first new install

    That contradicts the PC's output, unless the PC went for PE and suppresses the MAC derived SLAAC addresses.

    I dont know. I am no expert in this. I would be interested in learning more, but at this point, things get a little difficult. Somebody sent me a set of Netsh commands to use to shut down various things, and I have done that. I save that as a file.

    netsh int ipv6 set global randomizeidentifiers=disabled
    netsh int ipv6 set privacy state=disabled
    netsh int ipv6 isatap set state disabled
    netsh int ipv6 6to4 set state disabled
    netsh int teredo set state disable

    Is there anything else I should do . Darn this. Question mark comes out as .

    MS is doing it their own non-standard way, as always. Shame on them! They generate a random interface ID instead of using the EUI-64 method, and they use only that random ID.

    Somebody sent me a set of Netsh commands to use to shut down various things, and I have done that. I save that as a file.

    netsh int ipv6 set global randomizeidentifiers=disabled
    netsh int ipv6 set privacy state=disabled
    netsh int ipv6 isatap set state disabled
    netsh int ipv6 6to4 set state disabled
    netsh int teredo set state disable

    Those changes are only temporary as long as the PC runs. To disable the random interface ID persistently:

    netsh interface ipv6 set privacy state=disabled store=active
    netsh interface ipv6 set privacy state=disabled store=persistent
    netsh interface ipv6 set global randomizeidentifiers=disabled store=active netsh interface ipv6 set global randomizeidentifiers=disabled store=persistent

    ciao,
    Markus

    OK, so wiill that also turn off the 6to4 and teredo?. I forgot to mention the last line in the instructions I got was to reboot after doing those netsh commands.

    No, for those you have to use the other commands, but in the same manner.

    Good! You now have a SLAAC address. An address that has the lower 64 bits derived from your MAC address. That should survive a system reset.

    Have that address linked to your host name and all will be A OK.
