The service that a Domain Name Server provides can be thought of as a Directory Lookup Service as they maintain a Directory of Domain Names. Given a name the Domain Name Server is able to return the IP address corresponding to the name (assuming there is a matching entry in the Directory).
Indeed, After you install Active Directory on a server that's running the DNS service, you can use the DNS Management Console to verify that the appropriate zones and resource records are created for each DNS zone. Active Directory creates its SRV records in the following folders, where <Domain_Name> is the name of your domain: Besides, To verify basic DNS functionality: On the domain controller that you want to test or on a domain member computer that has Active Directory Domain Services (AD DS) Tools installed, open a command prompt as an administrator. To open a command prompt as an administrator, click Start. In Start Search, type Command Prompt. In respect to this, In Azure Active Directory Domain Services (Azure AD DS), a key component is DNS (Domain Name Resolution). Azure AD DS includes a DNS server that provides name resolution for the managed domain. This DNS server includes built-in DNS records and updates for the key components that allow the service to run. Accordingly, With a single DNS server this is fine but with you should avoid using this configuration with multiple DNS servers, especially with Active Directory Integrated zones. Always change the DNS servers to the IP Address of your DNS Servers.
