You could use RPZ for the entry "www.google.com" and then the rest of the
domain would resolve from the internet.

Hello again BIND-users,
Sorry for asking for help twice in one day.
We are setting up a new resolver performance test bed, one that we hope will be
a better simulation of real-world deployment. Once we have this working, we
should be able to profile BIND performance using DoH and DoT as well
Hey there BIND Users-
We have removed the ISC custom SPEGNO implementation from the development
branch (9.17.x). We intend to also remove it from BIND 9.16 and 9.11. This is
very old and fragile code and it is provides extra risk for everyone, while
being useful for (we think) almost nobody.
But if I want to resolve:
foo.google.com
that doesn't exist in my google.com private zone, I don't obtain any result.
I need to tell my private BIND to forward to 8.8.8.8 all the received
*.google.com queries, except www.google.com that is the one locally
resolved.
Thanks again !!!
El mié, 31

This is probably due to NOTIFY messages not working. NOTIFY is the
mechanism that allows primary servers to tell secondaries to

Sorry, crisis (not named related)
I will post sections of the named.conf later if needed, but will answer the
simple questions now.
I don't know what the propagation delay is, notifications are enabled, when the
primary reloads a zone the secondary gets notified and requests a zone xfer.
The flags, services and regexp are each limited to 255 characters.
