#Configuration excerpt:
listen-address=127.0.0.1
listen-address=192.168.115.18
dhcp-range=192.168.114.100,192.168.114.250,255.255.254.0,6h

#dhcp-range=192.168.115.21,192.168.115.250,static
#dhcp-range=192.168.114.31,192.168.114.99,static,255.255.254.0,infinite

As soon as I activate one of the last lines, dnsmasq refuses to start with the error msg that the range was incorrect, although there is no overlap in range, nor is the range incorrect.
I am starting to think that this might be a bug, maybe dnsmasq cannot cope with subnets other than /24?

Thanks for your support!

dhcp-range for static ranges is

dhcp-range=<address>,static,......

ie, there's only one address before the static keyword.

Not a bug.
