Setting up DNS for several DCs in the same domain can be a challenge. There are a few options you can consider.

Option One: Use a Domain Controller as a DNS Server

One option is to use a domain controller as a DNS server. This will allow the DC to handle all of the DNS requests for the domain.

This is the recommended approach if you have a small number of DNS servers or if you want to centrally manage DNS.

One downside to this approach is that the DC will need to be online all the time in order to handle DNS requests. If the DC is unavailable, DNS requests will fail.

Option Two: Use a Centralized DNS Server

Another option is to use a centralized DNS server. This is a server that is located outside of the domain.

The DCs in the domain will use this server to lookup DNS addresses.

This approach has two benefits. First, the DCs can be offline for longer periods of time without affecting DNS service.

Second, this approach can be more scalable because it doesn’t rely on a single domain controller.

However, this approach has a couple of drawbacks. First, the centralized DNS server will need to be available at all times.

Second, this approach can be more difficult to manage because it requires a separate server for DNS service.

Option Three: Use a DNS Server on Each DC

Another option is to use a DNS server on each DC. This will allow each DC to handle its own DNS requests. First, it allows you to scale DNS services independently.

Second, it allows you to use a smaller number of servers.

However, this approach has two drawbacks. First, it can be more difficult to manage because each DC will need to be able to handle DNS requests.

Second, it can be more difficult to scale DNS services because each DC will need to be able to handle DNS requests.
