DHCPv6: Modify DUID type of Windows Client RRS feed

  • Question

  • Hello There,

    Is there a way to modify the DUID type the Windows client? The default value is DUID-LLT and we would like to change this to DUID-LL(type 3) or DUID-UUID (type 4).

    Sincerely yours

  • Hi,

    According to your description, my understanding is that you want to change the DUID type.

    In general, DUID = DUID type(4 digit) + hardware type + DUID generate data and time + MAC address. 

    The DUID type is a default setting by system. You may try to edit the DUID by editing registry key:

    DUID type value:
    0001 – DUID-TTL
    0002 – DUID-EN
    0003 – DUID-LL

    Remember to back up the registry before any changing. 

    Best Regards,
    Eve Wang
