I am trying to create a DHCP reservation based on a 20 character unique identifier (Not a MAC address)
When the client requests an IP address it does not get the reservation correctly.
I tried connecting to the DHCP server, obtained an IP address successfully, then went to the DHCP leases and right clicked the lease to create a reservation based on the unique identifier, but upon releasing and reconnecting I got a different address.
Also I have found that other people have been assigned the reserved address which is very mystyfying!
The 20 character identifier that is being used can potentially have the same first 12 digits, so I wonder if this is confusing the DHCP server as it could be expecting a 12 character MAC address.
