How to clear DHCP? If can't, suggestion!

Discussion in 'Broadband Hardware' started by Matthew Weyer, Sep 10, 2004.

  1. Hello everyone,

    I was just wondering if there's an easy way to clear the DHCP client list so I
    can assign different IP addresses to old devices (MAC addresses). If it's not
    possible except by resetting the device back to factory default settings then I
    have a suggestion, let us reset the DHCP server easily. Thanks!

    If you are using DHCP you shouldn't care what IP address is assigned to a
    PC. DHCP servers tend to give out the same IP address based on the MAC
    address (assuming the same IP address is still available) for a reason -
    probably to accommodate people who mistakenly use the IP address to get to
    the box; eg: http://192.168.0.101 etc. rather than using other ways to
    identify the target - or to avoid breaking any drive mappings etc.

    Anyway, if you *need* to know the IP address of a box behind a router, then
    define the DHCP range differently to exclude some handfull of addresses and
    assign the boxes a static IP in the unassigned range. That is why one can
    define the scope of the addresses that are handed out by DHCP.

  3. Thanks Kerry! Actually the only reason I want to clear the DHCP client list is
    because I have a lot of people connect to my network over time and have so many
    addresses on there that it's hard to tell what's what.

    I can see that could be a hassle... Not sure MS is even accepting
    suggestions anymore for their now-defunct product line (as if they ever were
    accepting suggestions!). I did not mean to belittle your suggestion (now I
    realize I may have given that impression after I read my own reply!! - oops,
    sorry). An option to "restart" the DHCP server code would be something that
    would be nice (sure beats resetting from factory and then restoring your
    saved settings).

    Are you sure that a power off/on recycle doesn't clear the DHCP table? I
    must admit I have never looked, but I would imagine it strange that the
    router would save that info in non-volatile ram... but then again...

    cheers

    The easiest way to to do a soft reset by unplugging the power & plugging
    it back in. It's much easier then a factory restore as you only lose
    the basestation log, time, DHCP client list, etc.
