I don't know if this is even possible, but here's what I'm trying to do:

We have a single subnet set up (10.10.0.0/16)
we're using 10.10.0.1/24 as our static range
I would like to assign a certain batch of computers to the 10.10.10.1/23
range, and another batch to 10.10.8.1/23 range based on what group the
workstation is is in eDirectory

I have the various ranges set up as address ranges, and until now have
been manually entering IP Addresses into the DNS/DHCP console via MAC
address. Is there any way to set this up automatically?

Thank You
