    Simple DHCP Question

    Sorry - brain gone.

    I want clients to pick up an address in the range 10.xx.yy.30 - 10.xx.yy.200

    and I want reservatations for printers,APs etc e.g 10.xx.yy.10, 10.xx.yy.11 up to 10.xx.yy.29

    I don't want muggle clients knicking IPs between 10.xx.yy.10 and 10.xx.yy.29..
    Shoudl I set my pool to be 10.xx.yy.10 - 10.xx.yy.200 and exclude 10.xx.yy.10-10.xx.yy.29

    or

    just set pool to 10.xx.yy.30 - 10.xx.yy.200

    or
    something else?

    Si

    It depends on whether you want to explicitly set reservations for your printers in DHCP.

    If so - make the range 10.xx.yy.10 --> 10.xx.yy.200 - and then set reservations from .10 --> .29 for all your printers (you'll need to know the mac addresses though).

    Personally - I just give my printers fixed IPs (manually... not via DHCP) and use a different range for clients.

    If you are statically setting the IPs on the printers, APs etc then you could have the pull from .30-200 without dealing with exceptions/reservations that way.

    If you want the printers, APs etc to pick up their IPs from dhcp then you will set the pool from .10-200 and put in your reservations for those devices.

    Trouble is - muggle clients are knicking addresses below 10.xx.yy.30 so I now can't add in more reservations without finding the offending client and switching it off and then deleting the lease and re-assigning it as a reservation

    But the other computers are knicking addressess I just want to use for reservations (see above)

    Set you're range 10.xx.yy10-10.xx.yy.200 and set an exclusion range of 10.xx.yy.10-10.xx.yy.29 and then that way you can have clients picking up the correct addresses while you set up reservations for your printers and what not.

    You should know the name of the machine from the DHCP lease if you want to go kill it off + add the exception.

    Or you could add an exclusion range and pop your printers/APs in there.

    Might find when everyone's gone home this becomes easier

    Maybe my brains worse than I thought I even the questions come out wrong

    Can I add an exclusion range but still be able to add reservations within that exclusion range or will DHCP says get stuffed!

    I dont want normal DHCP clients using the the lower ip numbers for themselves but I still want the facility to use reservations instead of static IPs.

    (My experience of static IPs on devices is that one day - they will forget them and then peopl can't print )

    You don't need to add an exclusion range - that would be used if you didn't use reservations but put static IPs on devices.

    Just set up your range, then put in all of your reservations and then hey-presto!

    I hope this is as humerous to others as well as me

    I WANT PRINTERS AND APs TO BE GIVEN SAME ADDRESS EACH TIME USING RESERVATIONS in range 10.xx.yy.10 - 10.xx.yy.29 (I KNOW HOW TO ADD A RESERVATION - I DO THIS ALREADY)

    I WANT NORMAL COMPUTERS TO GET 10.xx.yy.30-10.xx.yy.200.

    I DONT WANT NORMAL COMPUTERS BEING ASSINGED IPs in 10.xx.yy.10-10.xx.yy.29 address space

    what to I set my pool to?

    Ok... I see... normal clients are nicking the addresses before you reserve them.

    So... do this:

    1. Set up your pool as 10.xx.yy.10 --> 10.xx.yy.200.
    2. Add an exclusion range of 10.xx.yy.10 --> 10.xx.yy.29
    3. Activate your scope.
    4. Add your reservations as and when you need to.

    That's it.

    Drink coffee, eat bacon and be happy.

    @pantscat and dazzd88

    Super - that's worked - I added the exclusion and then reserverd an unused address in the exclusion range for my new printer and power-cycled it - it picked up reserved address OK ( the naughty muggle clients will move out of space over the next 2 weeks )

    Drink coffee, eat bacon and be happy.
    Ah - I see where I've been going wrong - I've been drinking bovril and eating coffee flavoured chocolates!

    Sorry about the confusion... I'm not very good at multi-tasking without coffee!
