An Introduction to PTR Records: What They Are and Why They Matter?

What are PTR Records, and How Do They Work?
PTR records, also known as Pointer DNS records, are pointers that connect an IP address to a domain name. They are used to verify that the IP address belongs to the correct domain name. When you send emails or run a web server, the emails or web requests must have a properly configured PTR to be correctly delivered. The PTR works similarly to a regular DNS lookup, except that instead of finding the domain name from an IP address, it finds the IP address from a domain name. When the server looks up an IP address, it will also look up the corresponding PTR record. This allows the server to verify that the IP address is associated with the correct domain before allowing the request or email to be delivered.
