WhoisXML API’s Academic Research Program

Data gathering in most academic research projects can be tedious and daunting. As reliable and trustworthy research findings depend heavily on accurate and comprehensive data, our domain, IP, and DNS sources have helped researchers allocate more time to data analysis than collection and cleansing.


With our Academic Research Program, researchers can access extensive data within minutes from multiple Internet and cyber threat intelligence sources. We offer several consumption models to choose from—API, data feed, or web-based GUI.

Why take part in the Academic Research Program?

  • Access accurate and updated cyber intelligence

    Data accuracy is key to a successful research project. Our continuous data crawling and partnerships with other data providers allow us to keep our data updated and accurate. Our domain, IP, and DNS datasets cover the vast majority of TLDs, ccTLDs, and active IP addresses, translating to billions of WHOIS and DNS lookup records.

  • Get data from reliable providers

    We partner with multiple security intelligence companies, ISPs, registries, and registrars through sound and comprehensive data exchange programs. Taking part in the Academic Research Program allows you to access the data from these entities as well.

  • Retrieve processed and readily consumable data

    Do not spend too much time parsing data and converting it into uniform formats. The data we provide is already well-parsed and available in widely integrable formats, such as CSV and JSON.
