There are couple of ways to do such configuration.
One easy way is to increase IP lease time in /etc/dnsmasq.conf file as follows.
One easy way is to increase IP lease time in /etc/dnsmasq.conf file as follows.
Look for dhcp-range option, and change last value "12h" to "infinite" e.g. change
dhcp-range=192.168.100.60,192.168.100.240,255.255.255.0,12h
to
dhcp-range=192.168.100.60,192.168.100.240,255.255.255.0,infinite
Another way of binding MAC and ip is by adding 'dhcp-host' entry in dnsmasq.conf file
for example:
dhcp-host=11:22:33:44:55:66,192.168.0.60
Once dnsmasq.conf file is updated, restart dnsmasq service using
service dnsmasq restart
