    I am not sure I follow your problem.<br>
    <br>
    As long as you keep your leases file, one MAC should always get the
    same IP, except if it has been given out since last time that MAC
    was seen. The only reason it would be given out again is if you run
    out of IPs.<br>
    <br>
    So if:<br>
    - you always retain the leases file<br>
    - have enough IPs that it will never be necessary to reuse IPs<br>
    then the default behaviour (mandated by RFC) is to always give the
    same IP to a MAC.<br>
    <br>
    I assume you see the problem? What does it look like when it
    happens? Any specific way to make it happen?<br>
    <br>
    The leases file is added to every time something happens to a lease
    - and at some interval a new file is written with the current
    content of the in-memory tables. So the last entry in the leases
    file is the valid one.<br>
