[Dnsmasq-discuss] unable to resolv hosts by name in my local network

Ok, this is true. But my question is different, i think.
If in /etc/hosts are present my hosts, with expandhost option in my dnsmasq
config, resolv by name work properly.
But I don't want to specify anything in /etc/hosts. I think that dnsmasq,
when one client get address, obtain all info (dhcp.leases) to permit itself
and other clients to resolv by name the new client, is it true?
