Accepted Answer

Ans. The back-end programming in DNS configuration refers to the use of scripting or programming languages to automate and manage DNS-related tasks. This can include tasks such as dynamically updating DNS records, integrating DNS with other systems or applications, and implementing custom DNS features. Back-end programming allows for greater flexibility and control over the DNS configuration process.

5. Can I use a primary DNS server for multiple domains?

Accepted Answer

Ans. Yes, a primary DNS server can be configured to handle multiple domains.
