The below assumes that a client can use a fix IP address even though it is configured on the DHCP server as DHCP static lease.

Is it possible to tell dnsmasq not to use one IP address in a dhcp-range assignment? I have a user on my LAN who has set 192.168.1.121 in their system as their IP address and it's in my dhcp-range=192.168.1.80,192.168.1.223,12h
You could split your range in two smaller ranges living out the IP in question.
(I think they originally used dnsmasq's DHCP to get 192.168.1.121 so it's unlikely to get re-assigned but better safe than sorry)
You could also make Dnsmasq awair of this IP by having a fixed DHCP lease by using MAC addr/client ID.
As a follow-up I guess that if I want dnsmasq to return a system name for 192.168.1.121 (which it hasn't assigned itself) I'll need to add it to /etc/hosts on the dnsmasq system.
I would use 'dhcp-host' instead of the hosts file. -- John Doe _______________________________________________ Dnsmasq-discuss mailing list Dnsmasq-discuss@lists.thekelleys.org.uk http://lists.thekelleys.org.uk/mailman/listinfo/dnsmasq-discuss
