<p>Hello All</p>

</p>
<p>Is there a configuration for dnsmasq to have a primary and
fail-over. Meaning if my dnsmasq server (dhcp and dns) go
offline can another machine running dnsmasq be configured to ?</p>
<p>"takeover" dhcp/dns roles of the primary ?</p>

I've done this, although somewhat manually. Essentially, I use
Ansible to ensure that my configs are all in sync. Then, I use
pacemaker to detect a 'host down' situation. This moves an IP alias
and then clients start hitting that host. <br>
<br>
You may be able to stick nginx in front of dnsmasq and
load-balance.... but, if you're using dynamic DNS updates and you
rely on a leases file, you could get different answers based on
which server you hit (that'd be bad). If all you are doing is DNS
definitions and nothing dynamic, I don't see why it wouldn't work...<br>
