I've gotten everything configured and I have a client pulling a DHCP address but I’m not able to resolve it’s name in DNS using dnsmasq as the name server. I can resolve entries in the /etc/hosts file without any issues.</div><div class=""><br class=""></div><div class="">From what I can tell, the DHCP client name is being passed successfully from the client to the server (as it’s visible in the dnsmasq.leases file).</div><div class=""><br class=""></div><div class="">I’ve included my current configuration below, am I missing some configuration option that enables DHCP clients to register themselves into dnsmasq ’s DNS?</div><div class=""><br class=""></div><div class=""><div style="margin: 0px;
