We have over 23.8 billion historical WHOIS records obtained from tracking more than 774 million domains across more than 7,596 top-level domains (TLDs). More historical data is added to our domain history database every day as we continue our data crawling activities.
Our data gathering methods have been perfected after more than 15 years of data crawling. We provide accurate and reliable WHOIS history intelligence to thousands of happy customers.
We want to make it easy for customers to use our domain ownership history data. As such, our historical WHOIS database is already clean, parsed, and structured, making it readily integrable into existing systems.
A WHOIS history database, also known as a domain history database, is a repository of WHOIS records used to track historical domain registration changes and ownership details prior to WHOIS record redaction.
“Whois XML API products represent an invaluable resource for security researchers, seamlessly integrating within complex pipelines with ease.”
“Your history lookup is a life saver. I’m a web designer with a client who lost track of one of their important domain names. Using your web-based WHOIS history search, I was able to prove they do indeed own the domain and assist them with their registrar account recovery process. This was sort of a one-off for me, but if I face a similar situation in the future, I’ll definitely come back to make further use of your amazing tools and resources.”
“We want to provide all Cyberscape users the ability to integrate relevant data for their cyber threat investigations. WhoisXML API provides unique data that will be helpful to the cyber threat investigation community, allowing analysts to shorten the cycle of understanding and mitigating threats.”
“WhoisXML API offers a comprehensive suite that can serve as a one-stop shop. Furthermore, the team is very supportive of the academic research community, and overall responsive to customer inquiries!”
“The WhoisXML History API has been a game changer for our online investigations, trainings, and books. We have uncovered the true owners behind numerous malicious domains, even though they currently possess "private" Whois registration.”
“Whois XML is one of the most important tools we use for domain intelligence in the Bachelor's Degree program in Investigation and Security Sciences at the University of Perugia. In particular, we appreciate the reverse research from IP to Domain and Whois with query filters. The tool is comprehensive, providing detailed information such as phone numbers, names, and other details from Whois records. While many Whois records are now covered by privacy regulations, WhoisXML API provides access to all historical WHOIS records.”
“WhoisXML was the game changer for us. It has revolutionized our ability to disrupt cybercrime in process and at scale by quickly identifying all of the vendors providing material support for scammers using sophisticated website templates that look legitimate. By quickly identifying the vendors unknowingly supporting the criminals, we can provide them with public interest justification to burn down the criminal infrastructure.”
“WhoisXML API is amazing for checking out the historic registration information of a domain, pivoting to locate the alternate registrations with the same details and also my cyber investigations. The data proved very useful when investigating pig butchering scams and domains that host child abuse material.”
“Very useful for investigations, we can go back in history and see when domains were registered and who owned them at a certain time.”
“WhoisXML API builds out data sets that help users correlate attack infrastructure with related IP and WHOIS information.”
