[Dnsmasq-discuss] ethers should have precedence over client dhcp request

I have the situation that I changed the ip address in /etc/ethers. However
when the client sends a DHCPREQUEST with its old address (because the lease is
still valid) dnsmasq sends a DHCPACK and renews the lease. Therefore the
client could use the ip indefinitely. Is that correct or did I misinterpreted
my logs?

What I would like to see is that /etc/ethers has precedence over the lease
file. If a new DHCPDISCOVER / DHCPREQUEST comes in, dnsmasq should check the
ethers and offer only the ip address which is written there.
