Wondering how reverse address lookup technology works?

You’re at the right place.

In this article, we break down what exactly is a reverse IP lookup, and share how you can use this to generate more leads for your company.

Reverse address lookup might sound like a complex concept, but don’t worry – it’s actually pretty simple.

You don’t need to be a coder or have any sort of technical expertise to use reverse address lookup to your advantage.

Ready? Let’s jump right in!

What is DNS?

Before we answer the question of what is reverse address lookup, you’ll need to familiarize yourself with DNS.

DNS refers to Domain Name System, and Wikipedia defines this as “a hierarchical decentralized naming system for computers, services, or other resources connected to the Internet or a private network.”

If that’s too confusing, don’t worry – just think of DNS as an address list of computers that are connected to the internet.

Now, you already know that every device that’s connected to the Internet has a unique IP address that acts as their “identifier”.

Without DNS, every time you want to access a website, you’d have to type in their Internet Protocol address, which might look something along the lines of:

But because DNS translates domain names to IP addresses, we don’t need to go to all that hassle of memorizing lengthy IP addresses.

Instead, we can simply type in Forbes.com into our address bar, and get redirected to the site!

What is reverse DNS lookup?

Now that you know what DNS is, let’s talk about reverse DNS.

Before we go any further, let’s just clarify something…

All the following terms:

  • Reverse DNS lookup
  • rDNS lookup
  • Reverse address lookup
  • DNS lookup
  • Reverse lookup
  • Reverse IP lookup
  • IP lookup
  • Reverse IP address lookup

…they refer to the exact same thing.

Got it? Great.

Now, with reverse address lookup, you’re basically looking up internet hosts with their IP addresses.

There’s one caveat here…

The address you’re looking at has to have a valid Reverse DNS in order for this to work. As long as that’s the case, you can simply type in their IP address into your browser, and you’ll be redirected to their site.

If they don’t have a reverse DNS record, though, you won’t be able to identify where your visitor is coming from.

What has reverse DNS got to do with generating leads?

Well, everything!

Statistics show that, on average, a whopping 98% of website visitors will leave a site without converting.

Some business owners and marketers will say that there’s nothing that you can do about that (short of installing an exit-intent pop up), but that’s not true.

You can use reverse address lookup technology to capture your visitors’ information and nurture them as a lead.

We’ve previously discussed how you can use reverse address lookup to identify someone’s IP address and hostname.

Now, here’s the tricky part…

Most people aren’t actually using a unique Internet Protocol address that they own.

Instead, they’re using an IP address that their Internet Service Provider has temporarily allocated to them (while they’ve got them on contract).

So you might be able to pinpoint your site visitor’s location using this address, but you won’t be able to tell who they are, exactly.

What do you do?

Simple. Use a whois search to reveal more information about the IP address!

For the uninitiated, whois is a system that allows users to look up the name and contact information of a registered website.

Here’s how it works:

When companies register a new domain name, they have to provide the registrar with their contact details.

This is mandatory; it’s not a guideline – if you don’t provide accurate contact details, or you “willfully fail to replace out of date data”, your registrar can actually cancel your account and take back your domain.

All domain registrars have to maintain the information of their registrants (known as WHOIS records), and publish technical records to an authoritative registry.

What does this mean for you?

As long as you have your visitor’s IP address on hand, you’ll be able to figure out their domain name, their company, and their contact info!

Reverse DNS can help generate leads in many different industries and can help with a number of different types of businesses. You could use it for everything from generating SaaS leads to automating your marketing for insurance leads.

tool for lead nurturing

You’ve got your lead information… what’s next?

Once you’ve got your lead information, the next step is to reach out to them.

Your lead might not be ready to buy right now, but that’s fine. The goal is to nurture them to the point where they’re ready to make a purchase.

Now, what most sales reps struggle with is persistence.

We get it…

If you call your lead twice, thrice, or four times, and they don’t pick up, it’s easy to get discouraged, and want to move on to the next name on your list.

But here’s what you need to know:

Statistics show that it takes an average of 18 calls to actually connect with a buyer.

So no matter what you do, don’t give up. Keep on calling and emailing your lead, so that you increase your chances of connecting with them.

Of course, you should also work smart, not just work hard.

How do you do this?

Well, an analysis involving 2,200+ companies shows that sales reps who reached out to their leads within an hour were seven times more likely to have meaningful conversations with decision makers.

What does this mean?

You don’t have the luxury of waiting on those leads, and calling them only when it’s convenient for you.

As soon as a new lead enters your pipeline, you should get in touch with them ASAP!

Before we sign off, let’s also talk about how you can optimize the emails you send to your leads.

First, you’ll want to use certain words that B2B buyers favor in your subject line. Some of the most effective words to use include:

  • Demo
  • Connect
  • Cancellation
  • Apply
  • Opportunity
  • Conference
  • Payments

You should also steer clear of these other words, which are proven to be ineffective:

  • Assistance
  • Speaker
  • Press
  • Social
  • Invite
  • Join
  • Confirm

Also, keep your subject lines short and sweet. More specifically, subject lines containing just three to four words get more responses than longer ones. Finally, remember that your conversation with your lead should be a two-way street.

You don’t just want to talk at them and bombard them with a ton of information…

You want to ask them questions, and demonstrate interest in their company as well. If you include one to three questions in your email, you’re actually increasing your chances of getting a reply by a whopping 50%.
