DHPC and static IP addresses

[rua17]

In the past we used static ip addresses in our clients, but the management
of this is becoming unbearable. So we installed DHCP server and configure
the new stations with dynamic IP's.

The problem is that the DHCP server is giving already taken IP addresses. Is
there any way to tell the Server to look up first in order to find if the
address is already in use?

we set up the Conflict detection attempts to 3 but it's not working

TIA

Use have to use Exclusions in the DHCP Scope to not allow it to give out
addresses that are already statically in use.

You have to start out by looking at your IP# Listing to see the used address
vs the unused ones. Create the DHCP Scope using the full address range but
then use Exclusions to prevent it from using your staticaly assigned ones.
Then in "small groups" set your machines to use DHCP. Do this to the point
where most of the free "dynamic" addresses are used up. You can now
re-adjust the Exclusions so that the DHCP can now hand out the additonal
addresses that have been "freed up" buy the previous machines being changed
from static to dynamic.

You can continue this process until you get it to the point where you want
it.

You could set up your DHCP server to give you a different range of addresses than those you set manually, allways in the same network.

You used to give your clients IP addresses like xxx.xxx.xxx.001, 002, 003, etc. well you could set your DHCP to give addresses between xxx.xxx.xxx.100 and 200 as an example, so your DHCP will never give an address that coincide those you already have, but it have temporaly until you set all ip address to dinamic.
