Significantly Enhanced Usability Allows More Precise Searching Across DomainTools’ Market-Leading Whois Data

"We use Reverse Whois from DomainTools to strengthen our anti-counterfeiting cases. It's an invaluable tool to link websites together, and the new UI makes that even easier.

DomainTools, the worldwide leader in domain name and DNS data and research tools, today announced the release of a significant update to its market-leading Reverse Whois domain ownership research tool. The new Reverse Whois product features a number of significant improvements including more surgical control of input queries, the ability to filter on terms in the domain string itself, and increased insight into the result set prior to purchase.

Reverse Whois is a powerful tool to reveal connections between domain names and domain owners. Terms that describe a domain owner, such as an email address or company name, are entered into DomainTools’ Reverse Whois tool and, in return, users receive a list of domain names associated with those terms.

Brand agents can prioritize their enforcement activities with the complete list of domain names owned by a counterfeiter or cybersquatter. Attorneys can use Reverse Whois to establish bad faith and support their UDRP filings. The ability to search domain names by ownership record makes Reverse Whois an invaluable tool for due diligence research and corporate domain management. "We use Reverse Whois from DomainTools to strengthen our anti-counterfeiting cases," says G. Roxanne Elings, Partner, Davis Wright Termaine LLP. "It's an invaluable tool to link websites together, and the new UI makes that even easier. With the new Reverse Whois, we can enter all the terms a counterfeiter might use in their Whois records and avoid buying multiple reports with overlapping data."

“Reverse Whois, a product DomainTools pioneered over five years ago, continues to be one of our most frequently used research tool among clients who demand the largest and most accurate data set. The product improvements in this release are focused squarely on making Reverse Whois even more indispensable for domain research, monitoring, and investigative needs,” says Tim Chen, CEO of DomainTools. “DomainTools is already well-known for having by far the best database of current and historic Whois records available anywhere. Applying powerful research tools like Reverse Whois on top of this data store allows us to unleash the true potential of the data for our clients.”

Significantly, DomainTools is also introducing a very limited trial of the new Interactive Research Mode for Reverse Whois. Enterprise-level users with access to this mode get unlimited Reverse Whois lookups at a fixed monthly price. This type of access lets researchers rapidly iterate between connected domain names to interactively refine their search and quickly build a comprehensive result set.
