I am planning a new DNS names structure inside of our corporate network. We have external registered DNS name (e.g. example.com) and internal-only not existing name (e.g. exampleinternal.local). Everything internally is hosted on Windows 2012, DNS server + AD (one domain).
Now we would like to use only our external name.
The idea is to create the domain under
internal.example.com and make it the root of our internal DNS.
This would mean that all internal clients will resolve into
host.internal.example.com and they will be kept by our internal DNS server. At the same time we have other hosts, like
something.example.com which are kept on the registrar's DNS server.
Thus I have a question. In case we would like to use this schema (domain delegation is not allowed on our registrar), would it be resolved correctly by our internal DNS server?
1. Client machine (inside our network) is asking for internal service:
This is for sure will be resolved by our internal server into local IP
- Client machine is asking for external service:
www.example.comWould our internal DNS server forward request to the ROOT servers or Forwarders in this case? Are there any requirements for forwarders (do we need to setup our registrar's NS as forwarder)?
Thank you for answer.
