[Dnsmasq-discuss] How does the "unqualified domains" feature work?

[Data Control Systems - Mike Elkevizth]

Hi,

I am wondering how the "unqualified domains" feature works in dnsmasq. Also,
is it possible to have more than one server specified for a certain domain?
Dnsmasq doesn't seem to complain about this, but it also doesn't appear to
work as I figured it would. Here is my poblem. I have three servers in
remote locations - which may loose connection from time to time - that I
would like to be able to have look up address from each other that they have
leased to clients via DHCP. I tried using the search domain feature on the
host computers, but that is way to slow. So what I thought was that if I
could use the unqualified domain feature, it should do the trick. If the
simple name looked up is not in the local servers leases (or hosts file)
then it should forward that request to one of the other servers (setup as an
unqualified domain upstream server). The only problem is that I don't know
if this could cause a type of loop where server A forwards to server B which
then forwards it back to server A and so forth. The only way this should
happen would be if the server didn't have the name and then I would assume
the first server would break the loop by timing out. But, would it also send
an upstream query to the third server? The address that the host would be
requesting would have to be on one of the three or it doesn't exist. I can't
see any other way to accomplish what I want, but I'm up for suggestions.

Thank You,
