Dialog Adds Searchable Database of Internet Domain Names

Exclusive New Global Service "Invaluable" for Intellectual Property Research and Tracking

LONDON (3 December, 2002) — Dialog, a Thomson (NYSE: TOC; TSX: TOC) business and a leading worldwide provider of online-based information services and integrated information solutions, today announced the launch of a searchable database of more than 65 million current and historic Internet domain name records. The database includes records for about 20 million currently active domain names, with most containing detailed "Whois" information.

Dialog made the announcement at the Online Information 2002 conference, the world's largest gathering of information industry professionals.

A domain name is an alphanumeric name or Web address used to identify a particular site on the Internet. The Whois record attached to a domain name is part of a publicly available registration document that lists registrant and technical information for each domain name.

The new Dialog service is the largest and most robust database of its kind available.

Unlike the simple domain name look-up services available on the open Web, Dialog subscribers may search from more than 50 indexed Whois data fields contained in domain registrations, including the registrant's name, corporate affiliation, address, phone number and specific technical information such as IP addresses.

The domain names database might be used by Dialog subscribers for:

  • Trademark clearance, litigation and infringement investigations
  • New product development
  • Audits of domain names during merger or acquisition due diligence
  • Maintenance of product names and internal corporate domain name inventories
  • Monitoring competitors
  • Criminal investigations by law enforcement officials, including cyber crime.

Unique to the new Dialog database is historic information that allows users to follow trails of domain registration transfers and changes. For example, a user might search by a single e-mail address or company name to pinpoint domain names associated with that piece of data, and then track transfers or other changes to that registration.

The new content source is available through the online services DialogWeb, DialogClassic and DialogLink.

Wide-Ranging Business Applications

"The Internet has clearly become a fixture in the everyday life of many professionals. This database — the most comprehensive collection of domain names available in the market today — gives our users around the world tremendous new leverage to research current and historical domain name registration information," said Viji Krishnan, Dialog's vice president of content.

"This is an invaluable tool for intellectual property management, as well as for a host of other applications.

"But there really is no limit to who can harness our new service," Krishnan added. "The ability to research domain names extends to literally every aspect of business and beyond. Just as the Internet is central to so much of our lives now, so too is the ability to monitor and track the backgrounds of domain name owners."

Broad Coverage and Multiple Database Searching

Containing more than 65 million records — a number Dialog says it expects to expand in the months ahead — the new database, File 225, is now Dialog's largest single database.

The database includes data from several leading registrars from around the world, including VeriSign, BulkRegister, DomainPeople, DomainSite, eNameCo, eNom, MelbourneIT, NamesBeyond and Tucows. Additional registrars will be added later, Dialog said.

File 225 may be searched as a single file or concurrently with other content and data sources available on Dialog services, such as patent and trademark information. Retrieved information may be sorted, ranked and reformatted in other ways, based on user needs. In addition, users will soon be able to set up ongoing Alerts for File 225, allowing them to receive notifications automatically when new relevant information (such as a competitor's name) has been added to the database.

The database initially will be updated monthly, though Dialog said it expects to move to weekly updates.

File 225 currently is limited to those domain names with the .com, .org and .net suffixes, also known as generic top-level domain (gTLD) registrations. However, Dialog plans to add additional gTLD registration data in upcoming months (those ending in .biz, .edu, and others) as well as country code top-level domains (ccTLDs — those ending in an abbreviation for a home country, such as .uk for the United Kingdom or .ca for Canada). (Note: Whois record formats vary among TLDs.)
