Uncover connections for all domains

Millions of domains are registered and traded each year. Ownership that is constantly changing, can make it difficult to figure out who holds the right to a website. So what if you need to determine the current owner? Or how can you find out whether certain businesses are connected?

We offer two solutions to tackle these problems.

WHOIS Database

Our WHOIS database can provide you with the information you need. We have ownership information on hundred millions domains including registrar-, DNS- and IP details. This information is all part of the official registration.


While the majority of all WHOIS information is correct, there are some limitations. The many changes in ownership can make it outdated, and not all registries make their data public. In addition, more and more privacy services offer ways to hide WHOIS information for their clients.

That’s why we have created Ownership. The tool is easy to use: just enter a website and track any domain back to its roots.

We offer information on:

  • Analytics ID
  • Websites hosted on the same server
  • Email found on the same website
  • Phone number or address (when these details are the same on more than 1 website)
  • Tax numbers found on the website
  • Bank account numbers found on the website
  • Websites hosted on the same IP address

Use Ownership when you want to buy a domain and need to contact its owner, are looking to protect your intellectual property or are just interested in a business’ portfolio.

We index over 280 million domains in 50 countries all around the world. For each of these domains we collect contact details, technical aspects, hosting properties and much more. That’s how we can trace any domain back to its roots, and now so can you.

Our ownership tool is easy to use. Enter a website and quickly determine its owner, find affiliated domains and see unique attributes like IP address or Analytics ID. Need the data you’ve found for further analysis? Just save your dataset and export it to Excel for later use.
