Removing lease database file when dnsmasq is not running should be enough. But dhcp client can try to "renew" already assigned IP address and dhcp client (dnsmasq) can extend this lease if nobody is using requested ip address. So you should remove both *client* and *server* databases to prevent such situation. I think it is possible to configure dnsmasq to assign only configured ipv4 address for mac address. For dhcpv6 I have own dnsmasq patches which assign ipv6 address bases on mac address... -- Pali Rohár pali.ro...@gmail.com
