How to make AD DNS poll external NS servers?

Question

Domain Name System

There is MS AD-server with DNS in a network. On AD DNS there is a domain1.ru zone.
But in fact, this domain is served by external NS servers of the host.
This is necessary so that, for example, support.domain1.ru within the network is resolved to the internal IP address (10.xxx), and outside the network - to the external IP address of the office.
Somehow you can force AD ​​DNS to do the following in this case:
If the client requests the address of the host somehost.domain1.ru from AD DNS, but there is no such host in AD DNS - let AD DNS query the NS's of the host for the presence of the host there.
The hoster does not respond to AXFR requests, it is impossible to transfer the zone from its NSs to AD DNS.

Answer 1

DNS -> Forwarder
Not?

Answer 2

as Andrey Ermachenok
said , use the forwarder. these are the addresses of the dns servers that yours will access if the required records are not found.
Most small offices are like this all the time. I have dns in my office, which serves only the internal zone and the mx-record (which is obviously visible from the Internet), and it sends everything else to the "smart guys" (at least 8.8.8.8, as a banal example) and caches it at home

Answer 3

Как и говорили господа Андрей Ермаченок и Константин, используйте сервера пересылки.
