let me clarify: This buster machine acting like a 3d printer does NOT

I'm sure it's running dhclient.  do

      ls /etc/dhcp

and

          ps ax | grep dhc

You don't need to do anything on that machine.  Just install a dhcp
server somewhere on your network (on the router is conventional) and it
will give that machine an ip number.


At risk of repeating myself forever, I don't need an unstable address, I
don't want whatever the heck is left in the pool. Hosts files do that, dhcp 
doesn't. It just hands out the next number in the pool.  hosts files are
static. A forveer lease.


DHCP will only hand out the "next" ('unstable') address to a host that
currently has no valid lease AND does not have a reservation set on the
DHCP server.  Reservations are based on host MAC address.

Any host that has a valid lease will renew that lease indefinitely, at
lease half-life (and if the DHCP server happens to be missing at
half-life, retry at 7/8ths ).
Assuming I install a dhcp SERVER on this machine, how do I edit the client.conf on that machine to query this one?, and how to I enable this "reservation" on this SERVER so it hands out a stable address ONLY if the reservation matches? Point me at the docs please and I'll go away.
You claim I don't have to do anything to that printer machine, so I installed the ICC server here. I have done zip to the dhcpd.conf which looks as it it is fully disabled. Assuming I want a pool of 16 addresses, say from 192.168.71.100 to 192.168.71.115, what do I uncomment and fill in, in dhcpd.conf? 

If I'm going to have to do this, I want it done the approved way.
I want the server to only respond to the MAC address of that printer, no response to any other MAC that might come calling. 

Thanks all.
