[Dnsmasq-discuss] Some clients get wrong IP

[Claes Parflo]

Thanks. Seem to be: 
not using configured address 192.168.5.160 because it is leased to 00:14:d1:f1:2b:89

I emptied /var/lib/misc/dnsmasq.leases for all 4 cameras in my test and issued SIGHUP before powering on cam's. I gave new MAC bonding to check results and enabled logging.

Where else do I need to flush old IP? Do dnsmasq have other hidden storage?

Extract below.
