[Dnsmasq-discuss] no address available with static range and dhcp-host

[Nicolas Granger]

The version is 2.90 and the mac address is correct.

With a regular dhcp-range, dnsmasq pulls an ip from the range, not the 
one of the host.

$ sudo dnsmasq -d --bind-interfaces -i lan --except-interface=lo 
--dhcp-range=192.168.2.100,192.168.2.150,255.255.255.0 
--dhcp-host=ac:1f:xx:xx:xx:xx,192.168.2.19
