RE: Multiple server interaction with multiple subnets

Sorry, this doesn't really help because the dns queries are done without a
domain extension. Some of the workstations are notebooks that can move
around from subnet to subnet. I would like it to be that the user doesn't
have to know a separate domain name for each location if possible. I have
thought about doing it this way, but it would make it more difficult for the
users, which I would like to try and avoid. If this is my only option
though, I will have to live with it. Let me know if you have any other
ideas.

Thank You,

Mike Elkevizth

If your setup looks something like this:
192.168.1.0/24 -> .subnet1.mydomain.org
192.168.2.0/24 -> .subnet2.mydomain.org
192.168.3.0/24 -> .subnet3.mydomain.org
(so you might have hostA.subnet1.mydomain.org, etc)

Then each dnsmasq server can direct queries about subnetX.mydomain.org
to the correct server.

See this part in the conf:
# Add other name servers here, with domain specs if they are for
# non-public domains.
#server=/localnet/192.168.0.1
server=/subnet1.mydomain.org/192.168.1.254

Does that help?
