hi! I use dhcping to test if it works which sends a REQUEST. The computer I'm testing with has no lease at all but a fixed IP. AFAIK dhcping releases the it's address immediately after it gets the answer.
That's valuable information. I tried out dhcping, and it's a long way from being standards-compliant. It seems to attempt to renew a lease when doesn't exist. dnsmasq just ignores it (as you saw) in case there is another server on the network which does have a lease.
If you set the flag dhcp-authoritative in dnsmasq.conf or the command line then dnsmasq will reply. cheers, Simon.
