Hi,

Dnsmasq will give that same address after a power failure as long as it recognises the same machine. There are situations involving DHCP client-id options which can cause a machine to not be recognised when it reboots. Check the FAQ for details of this.
Sorry, I should have read it.
Can you give a specific example of behaviour which you think is wrong? Please include the logs of DHCP interactions which dnsmasq puts in the syslog.This afternoon we reboot a machine on a knoppix cd, the address get via dhcp is ok (15:26:16).
After that we reboot the machine (gentoo), but we do a hard reset so there are no dhcprelease, and the host get 10.0.0.7 as ip address instead of 10.0.0.14 (16:22:18).
In /var/lib/misc/dnsmasq.leases , there were 2 entries for 00:d0:b7:4d:d4:3a one for 10.0.0.14 and one for 10.0.0.7
That's surprising, but there must be good reasons to not thrust only the MAC address.
Thanks and sorry, for the false bug
