    Hello,
    I have a question regarding Duplicate Address Detection (DAD) and
    DHCP server on linux:
    Suppose the DHCP server will try to assign , when a lease expiters, an
    IP
    address which is already held by a differnet machine.
    What then ? will the DHCP server succeed with that ? does it try to
    send
    a gartutious ARP in such a case (from "0.0.0.0") and fails with
    assigning an already assigned address ? is it configurable ?

    I am the very popular dhcp serve (commmon in most distros) from isc,
    which is in http://isc.org/products/DHCP/

    I tried to find out about this in the docs and in the code, but could
    not
    find anything.

    Regards,
    Mark
