5 Best Domain WHOIS Lookup Tool (100% Reliable)

Do you want to find out who owns a domain name using a reliable tool?

The WHOIS Lookup database can show you who owns or manages domain names. You can also find contact information such as a name, phone number, and address.

This allows you to connect with the owner to make an offer, serve copyright notices, or even spy on the competition.

The issue is that some WHOIS Lookup tools don’t give you accurate information. And if the owner has domain privacy enabled, you won’t be able to find any information.

In this guide, we’ll show you 5 reliable tools that will let you run individual and bulk WHOIS searches. We’ve also included tools that will help you trace domain information even if domain privacy is enabled.

Before we dive into the list, let’s be clear on what the WHOIS database is and what you can get from it. Let’s get started.

What is the WHOIS Database?

The WHOIS database (also known as ICANN Lookup) keeps a record of anyone that has registered a domain name.


You can search for any domain name and find the owner’s personal details such as name, email ID, mailing address, and phone number. You’ll also find other details such as the registration and expiration date of the domain.

The database is managed by ICANN (Internet Corporation for Assigned Names and Numbers), the governing authority over the internet.

Now you may be wondering why all this information is made public. We’ve listed the top instances where the WHOIS Lookup database comes in handy:

  • Serves as a central directory for the ICANN and other network admins to identify and fix problems
  • Holds domain owners accountable for the type of website they set up using the domain name
  • Lets interested buyers track down the domain owner and make an offer to buy it
  • Makes it easy to serve copyright and trademark notices if someone has violated your license, plagiarized content, or ripped off your design

Now that you’re clear on what the WHOIS database is and why it exists, let’s dive into the best WHOIS Lookup tools that you can use.
