Temporary disable DHCP sub-range IP distribution


  • Hi

    I want to secure my DHCP Server on Windows Server 2012:

    It possible to enable/disable remotely only one specific range of IP distributions?


    I have a range –
    and a second range – to

    Now I want to enable/disable the distribution of the second range whenever I need. That means, that the first range needs to be unaffected and continues its IP distribution even when the distribution for the second range is disabled.

    How is this possible?

  • I do not catched fully what is the reason for doing this. Clients have leased IP from their ranges.

    IMHO it is better to say what you want and not to try unsafe way to "safety".

    Thanks for your question.<o:p></o:p>

    The entire network consists of fixed IP addresses.

    But there are temporary devices, which need dynamic IPs.<o:p></o:p>

    When no external device is present, I want to prevent the
    DHCP Server from accidentally distributing addresses.<o:p></o:p>

    Since there are two exceptions due to internal mobile
    devices which need dynamic IP addresses at any time, I cannot simply turn off the
    DHCP Server service, when no external device is present.

    (These two internal mobiles have got MAC reservations on the DHCP Server)<o:p></o:p>

    That’s why I want to enable/disable only the IP range for
    external devices manually on the DHCP Server.<o:p></o:p>

    Tell me, if you need any further information.<o:p></o:p>
