DDNS isn't done for fixed-address clients. Nor is a lease file entry 
created for them - basically there is no lease recorded and no lease 
lifetime processing is done.

If you want a client with a fixed address but lease processing, then 
consider creating a reserved lease.

Either create a skeleton lease with the reserved flag set, or add 
reserved to an existing lease. This can be done by stopping the 
server and editing the leases file, or I think it's been said that it 
can be done via OMAPI.
