[Dnsmasq-discuss] Renewing pool addresses inspite of static configuration?

[Christian Peter]

hi,

we have a problem with machines keeping their old pool IPs and 
ignoring their newer static IP configuration:

there's a bunch of machines that got their initial IP address from a 
DHCP pool range.

later on, i configured other, static addresses for them via /etc/hosts 
and /etc/ethers entries.

unfortunately, the machines do not change their IP. the DHCP clients 
send DHCPREQUESTs for their previous addresses which are ACKed by the 
server.

restarting the server and clearing the server-side lease cache doesn't 
help. (there are some appliances among the hosts; so i can't clear the 
lease cache on the client side.)

is this a known bug/feature of dnsmasq?
is there any way i can enforce the IP change?

we're using dnsmasq 2.45 as shipped with SUSE Enterprise 11 SP2.

thanks for your help!
