https://activedirectorypro.com/dns-best-practices/
Here are some tips we recommend when managing DNS records: Have at least two internal DNS servers. Use Active Directory Integrated Zones. Configure the best DNS order on domain controllers. Domain-joined computers should only use internal DNS servers. Point clients to the closest DNS server. Configure aging and scavenging of DNS records. Set up PTR records. Make sure DNS updates are simulated and tested before overwriting an existing record. Remove DNS records not in use. Overwriting DNS records - Make sure DNS updates are simulated and tested before overwriting an existing record. One MUST also be aware of what the updates would do when they take effect.
