What does Reverse DNS mean?

Reverse DNS is an absolutely beneficial instrument for every business. It will convert the IP address into the domain name. But what makes you think you’d want that? Let’s take a closer look at Reverse DNS to comprehend it better.

PTR record – definition

The PTR is a DNS record type that we use for Reverse DNS to connect IP addresses (both IPv4 and IPv6) to the domain name. For example, when receiving mail servers want to know where an email came from, they execute a rDNS lookup and seek for PTR records. The PTR records will ensure that the IP address is actually associated with the domain name.

The purpose of Reverse DNS

Reverse DNS, also known as rDNS, is a querying technique used by DNS (Domain Name System) to do a particular sort of query with an IP address (IPv4 or IPv6) as an input and a name record as an output (A record or AAAA record). It’s termed reverse because it works in the same way as a forward DNS lookup, which connects an IP address to a domain name.

If you wish to check a specific host, you can use rDNS. Each host connected to a network has an IP address as an identification. You can readily see the IP address, but you can also execute a reverse DNS lookup to view the domain name and decide whether or not to trust it.

DNS zone: 4 Types You Should Know

Today we will talk about the DNS zone. First, we will explore its purpose and then its different types. Finally, we will explain how you can locate your DNS zone. Let’s start!

DNS zone description

A DNS (Domain Name System) zone is a database containing Resource Records from a single DNS Namespace. Another way to say it, these zones are designed to make administration simple and redundant while also assisting in improving availability and performance. Additionally, you could see the DNS zone as a horizontal platform that connects all of a corporation’s subdomains.

As an illustration, if we have the domain name picusha.net and a zone called picusha.net inside of a DNS server, we may construct Resource Records for all of the TCP/IP devices inside the zone. This DNS server has been given permission to handle all DNS requests for picusha.net domains, including www.picusha.net, info.picusha.net, etc.
