The purpose of a reverse DNS (also known as rDNS) lookup is to typically affiliate a domain with an IP address so you can identify a company visiting a website. This action can be performed every time a company lands on a site that has their IP address affiliated with their domain. Reverse DNS is the method of identifying the domain from the IP address. The importance of performing rDNS is due to the changing landscape of how we collect information, what information we collect, and what we do with this information. As the consumer market moves more towards an online presence, we can determine who is visiting our site, what messaging is resonating with our audience, if we are reaching the correct audience, and which companies you are attracting. This information, unfortunately, can not be learnt simply by the use of your website. By combining your site with other tools, you will be able to discover information about your visitors that will make your business more efficient and grow your sales.

What Does Reverse DNS (rDNS) Lookup Mean to Me?

Why rDNS should matter to you is because a domain is easier to remember than a random string of numbers. This makes rDNS lookup more valuable than DNS lookup. Email servers will commonly use the domain of a sender to block SPAM but can also use an IP address. But, most email systems will block mail from senders that do not have a domain affiliated with the sender. 

This is also important for B2B companies because if you are tracking your visitors to your site and tracking their IP addresses; you can identify the companies coming to your site. Through the process of rDNS, you can use this data to understand what companies are coming to your site and learn more about the companies that come and go without leaving a way for you to follow up. 

The process of rDNS

The process of identifying IP addresses can be tricky. Still, there are multiple ways to do so and numerous tools to assist you in this pursuit. Once the IP address of your visitors is discovered, you can start identifying the domains of these IP addresses or the locations of these IP addresses. It should be noted that the settings of the domains are not set by the servers but by the owner of the IP. This ensures that the information discovered is authentic and that you may act upon this data with confidence.
