Yes, the built-in ddns behaviour isn't satifying and we want to write
our own scripts for the events (but only the "on commit" event is
triggered for hosts witch fixed-address).
In our DHCP version ("Internet Systems Consortium DHCP Server
V3.0.5-RedHat"), the "reserved lease" isn't available...
In the meantime I found info on the scripts using "man dhcp-eval".

I assume you want to do something that the built in ddns doesn't handle

Use reserved leases ?
A reserved lease behaves exactly like a standard lease (ie it goes
through the same lifecycle) except that the address will never be
re-assigned to another client. I believe the only way to set it is to
manually edit the leases file to add the reserved statement.
