RegistryFusionTM unified Whois

One access point. One data format. A world of possibilities.

RegistryFusion unified Whois provides a single, consistent, programmable interface to the Whois system. It takes your domain or IP address query, automatically finds the correct server, and returns consistent machine-readable results.

This unified interface enables a wide variety of advanced applications:

• Tracking domain registrations
• Checking domain name availability
• Advanced Whois web pages
• Detecting (credit card) fraud
• Investigating spam, fraud, intrusions, and other online misbehavior
• Researching Internet infrastructure and usage
• Locating users geographically

The RegistryFusion system currently offers a choice of three interfaces that you can install on your own machines:

• HexWhois .NET class library (COM-compatible)
• Whois XML Web Service
• Whois XML Proxy Server

Each provides essentially the same functionality, just with a different way of accessing it.

HexWhoisTM .NET Class Library

The class library offers maximum control of queries and returned data. You can use it from both .NET applications and COM clients.

Whois XML Web Service

The XML Web Service is an ASP.NET application that takes query input from an HTTP GET or POST and returns results as XML.

Whois XML Proxy Server

The XML Proxy Server runs as a Windows Service (no IIS needed) and listens on port 43, just as a regular Whois server does. It takes a simple string of input and returns the same XML as the web service.

• Separates header and footer text (terms of service, advertisements) from record text
• Parses record text into consistent, well-defined fields
• Returns an indication of whether a domain is available (i.e., whether the query found a matching record)
• Provides a means of limiting quantity and rate of usage by IP address
• Caches XML results in a SQL Server database
• Is regularly tested and updated for accuracy
• Includes parsing support for the 5 major regional registries (ARIN, RIPE, APNIC, LACNIC, AFRINIC).
• Includes parsing support for over 90% of .com, .net, and .org domains. See the coverage details.

Requirements

• Windows NT4 SP6a, 2000, XP, Server 2003, Vista, or later. The HexWhois .NET class library will also work on Windows 98 and ME.
• The web service requires Internet Information Server (IIS).
• Microsoft .NET Framework 1.0, 1.1, 2.0, or 3.0. (To see if you already have it, look for "Microsoft .NET Framework" under Control Panel -> Add/Remove Programs.) You can download it from Microsoft or get it through Windows Update.
