My DNS is running in a split DNS scenario.
Both publically and internally we have the same domain. Lets call it test.com
When an internal user goes to test.com they get a different response to the outside world. Both zones are hosted on seperate systems. However some things are only publicly available and not internally. These things are very dynamically changing.
intranet.test.com. is only on the DNS internally
public.test.com. is only on external DNS
I understand that there is a risk of leakage, but this is something I can, for the time being, live with.
What I need to know is if it is possible to use bind to have the internal zone (pulled out of AD dynamically) queried first and when this zone doesn't resolve what the user is seeking, that bind then pushes this query externally and stores it?
If Bind can't do this - can Unbound? And if so, how?
