Setting up and managing PTR records has become an essential part of establishing and maintaining reliable email communication. Learn more about what PTR records are and why they matter by reading our blog post.

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.

TXT records are an essential part of keeping your domain secure and up-to-date. To protect against malicious actors, get an email or website verification, or gain access to custom hostnames, a correctly configured TXT record is necessary. But what exactly is a TXT record, when do we use it, and what types of records exist? In this blog post, you’llyou’ll find out the answers to these questions and more so you can ensure your domain is always safe and secure.

What is a TXT Record?

A TXT record (or Text Record) is a type of Domain Name System (DNS) record that is used to provide additional text-based information about a domain name. This allows domain owners to publish certain types of information to the DNS, as well as configure server settings, such as email and website hostnames. When correctly set up, a TXT record can help protect against malicious actors and maintain the security of a domain. Additionally, because TXT records can be used to input custom values and text, the information stored in them can be used for authentication purposes, such as verifying a sender’ssender’s identity or preventing spam.
