WHOIS是什么？

尽管WHOIS全是大写字母，但是它并不是一个缩写词。顾名思义，WHOIS信息记录将会告诉你有关一个域名的所有注册信息。每一条WHOIS信息都记录着域名的相关细节，包括年限、注册状态（创建、最新更新和到期日期）、注册商和所有者。出于网络调查、市场研究、域名购买和竞争中监测等原因，用户们允许通过WHOIS信息获取域名所有者的联系方式。

“WhoisXML API’s rich repository of domain records will be invaluable for Cyware and joint customers, as it enables automated enrichment of domain and IP content via Cyware Orchestrate.”

Michael Bazzell

Owner

IntelTechniques

“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.”

Flavio Critelli

Distinguished Professor of Digital Forensics

University of Perugia

“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.”

Michael Roberts

“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.”

Loonie Reed

Certified Fraud Examiner and Computer Forensic Examiner

“The consistent and structured data provided by WhoisXML API made it possible to group and identify who is behind suspected fraudulent websites, being able to search by phone number, address or e-mail address used in the domain registration.”

Yannick Delsahut

“I appreciate your products that are useful for checking domain expiration dates.”

Christine Bejerasco

“WhoisXML API’s domain intelligence allows us to quickly integrate WHOIS lookups into our security heuristics and algorithms without having to worry about hosting services, staging and merging data, and the complicated task of normalization.”

Mohammad Ismail Daud

Student

UC Davis

“I used WHOIS API and Website Categorization API. Both tools are simple and straightforward to use. Some API providers have extra bells and whistles that they force you to use, but WhoisXML API is really easy to work with. It’s stable, and I can trust that it’s not going to flatline later.”

Kieran Kennedy

Head

Snowflake Marketplace

“Keeping track of new domain registration activity is essential in today's digital economy. We look forward to continuing our collaboration with WhoisXML API to help customer leverage critical domain insights in a secure cloud environment that aligns with their data privacy and governance requirements.”

Larry Cameron

President and Founder

Paradigm Intelligence Ltd

“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.”

Jacob Waltz

CEO/Founder

Intraframe

“Very useful for investigations, we can go back in history and see when domains were registered and who owned them at a certain time.”

David Pearson
