Hostentry in DNS server for other partner company

My organization has an AD-integrated DNS server. My organization is operating call centers for other companies. For our daily operations, we have to access the resources of the other companies with private IP addresses. Hence, we cannot access the resources without adding the host entries in the local clients in my organization. All the necessary network connections are in place(only required connections like to a particular heldesk website with private ip) .
Since there are multiple resources, I would like to achieve this using the DNS server instead of adding the host entries in each clients in my organization. I would like to resolve the other addresses apart from these entries of the the partner companies should be resolved using my forwarders(same like for any other addresses)
What is the best option to achieve this?
I intend to resolve the required private IP addresses of the partner companies using my DNS server, and all other public resources should resolve from the internet.
I would like to know how my dns server try to resolve my querry if my client machines are requesting a different hostname other than which I added manually
Example:
my dns server is :portal.local
I want to access a website called myhelpdesk.abc.com with a private ip 10.10.6.253, and I have only a connection to this IP address only.
I want to resolve this hostname in my organization using my DNS server instead of adding the host entries in each of my client machines, and all the queries should work as usual without any trouble.

Thanks,
Alex

    Hi,

    Thanks for posting here.

    Before we go further, I would like to confirm the following questions:

    Based on my understanding, the goal is that you want to resolve the hostname in zone "abc.com" by your DNS server which host zone portal.local. If my understanding was wrong, please correct me.

    Do you know the IP address of DNS server which hosts zone "abc.com"?

    And can DNS server which hosts zone "portal.local" connect to DNS server which hosts zone "abc.com"?

    Best Regards,
    Sunny
