[Dnsmasq-discuss] Overwrite a public domain with dnsmasq while preserving external records?

[Hans Schmidt]

Hello,

I have the following setup, and wonder if this is possible with dnsmasq:

I own a domain called example.com, which has some records on a public
name server, for example a MX record, an A or an AAAA record for
example.com directly, but also some subdomains.

I want to reuse this domain also for internal use, so that my machines
internally are having entries like workstation1.example.com and
workstation2.example.com. The only problem is that dnsmasq will block
the records which are not managed by dnsmasq, instead of forwarding the
requests to the external name server.

Is there a way to solve this problem? Or should I rather put my private
machines on a subdomain (letting dnsmasq manage it), e.g.
internal.example.com, then having workstation1.internal.example.com?

Thanks :)
