Hi Experts,

Question on  DNS forwarding:

If we have 2 internal DNS Servers ( say 192.168.0.1 & 192.168.0.2) and the IP addresses of 2 external DNS servers from our ISP, (say 10.0.0.1 & 10.0.0.2 as example)

what is the best way to configure the DNS forwarding on both dns servers / best pracice?
I'm specifically wanting to understand the ordering, significance and the process of dns resolution when trying to access the internet from an internal domain client

Thankyou

On your Primary and Secondary DNS Servers, under Forwarders section specify both of your ISP DNS address i.e 10.x.x.1 and 10.x.x.2

When your domain client access internet / dns ; it will go to your primary dns server (whichever you choose to be primary 192.168.0.1 or 192.168.0.2 ;

Make sure you specify your ISP DNS (Both of them) in both of your DNS servers.

PS : Your client would inquire the primary server address first for dns resolution, if primary isn't available it will move to the secondary ;

No, you will put your ISPs DNS addresses both of them in your forwarders on each of your DNS Server.
