yup it does sound netmask related although I still think it's a bug and not just a misconfiguration issue.<br>
<br>
I tried this:<br>
Server IP =<a href="http://10.161.254.158/24" rel="noreferrer" target="_blank">10.161.254.158/24</a><br>
dhcp-range=10.161.254.0,proxy,<wbr>255.255.0.0<br>
<br>
Then I restarted dnsmasq while networking was up, and it still replied to the DHCP clients, even though it shouldn't, as the /16 network that I configured is different from the /24 that I was using, right?<br>
<br>
Merry Christmas!<span class="gmail-"><br>

I am fuzzy on this, I have not haz coffee, so this is just to suggest a<br>
possible clue:<br>
<br>
I think, if dnsmasq has to guess at an IP range, it considers the<br>
_class_ of network the IP address it is given. so an address<br></span>
192.168.12.20 becomes <a href="http://192.168.12.0/24" rel="noreferrer" target="_blank">192.168.12.0/24</a> <<a href="http://192.168.12.0/24" rel="noreferrer" target="_blank">http://192.168.12.0/24</a>><span class="gmail-"><br>
<br>
your address is in a class A network. If you want a /24 subnet, tell<br>
dnsmasq /24.<br>
<br>
just a guess.<br>
Merry Christmas!<br>
