Are you searching on the web what exactly is PTR record and why do you need it? If yes, you are in the right spot. Why? Because in this article today, we will take a deep look at its main purpose, what is its structure and why it is so essential and needed for you and your business organization. So, let’s explore it.
PTR record – Detailed explanation
The aim of the PTR record, also known as a Pointer record, is quite specific. First, the IP address must be linked to the domain name. Furthermore, this kind of DNS record can effectively work with both IPv4 and IPv6 addresses. As a result, you can configure and perform Reverse DNS using the Pointer record.
This DNS record allows you to check and verify that the IP address you’re using belongs to the domain name. When it comes to sending an email, this is critical. Receiving mail servers frequently want to verify the email’s origin and run a reverse DNS lookup. As a result, they carefully study and search out PTR records.
What is its structure?
The PTR record has a simple and straightforward structure. Here’s an example of how it may appear:
- TYPE: PTR record — This indicates the type of DNS record.
- Host: 18.104.22.168 – This entry requires the IP address of the host. It is possible to have an IPV4 or IPv6 address.
- POINTS TO: mhcompendium.com – This field can be used to display the domain name.
- TTL: 1h – This is where you set the TTL (time-to-live) value.
What is the significance of the PTR record?
The PTR record, often known as a Pointer record, is a crucial component of the Reverse DNS system (rDNS). It allows for the creation of trust and validation for a domain name’s IP addresses (IPv4 or IPv6). Furthermore, it is required for the correct functioning outgoing mail servers. In that instance, creating and adding a Pointer record is essential because it contains the confirmation methods.
Your message will be sent to the spam bin if the recipient searches for the Pointer record and cannot locate one. Likewise, if you make a mistake in the configuration of your PTR record, the same thing will happen. It is not, for example, accurately associated with an A or AAAA record. So be cautious and take your time to ensure that everything is in order.
Furthermore, you should construct a Pointer record in a Reverse DNS zone if you want to send your emails without any problems (to not fall into the spam folder) and have your receivers receive and read them.
We can infer that you are now familiar with the main purpose of the PTR record, what it looks like, and why it is important for you and your business. So what is the following step? Next, apply them to your domain to lower the bounce rate of your sent emails. It’s not complicated. It’s simply a question of knowing what to look for.
