  1. Only applies to the class library
  2. "Full record parsing" means that the software will break record details (registrant name, phone number, email address, and so on) out into separate fields if parsing support is available for the Whois server. The Lite Edition is intended for users who only need the raw record text. Examples: Lite Edition XML output | Pro Edition XML output
  3. Only applies to the web service and proxy server, but accomplishing the same thing with the .NET class library is trivial
  4. Only applies to the web service and proxy server

Explanation of terms

Non-redistributable means that the license covers installation only on your own machines (or machines that you exclusively lease) up to the number specified by the license type. With this license, you may not include the Whois interface as part of a product sent to other parties.

Internal use means that the Whois interface should only be used by your own personnel for internal applications. With this license, you may not offer parsed Whois data as a service to other other parties.


  • You may publicly display raw, unparsed Whois records
  • You may provide public services that make use of the Whois interface behind the scenes
  • You may display up to 5 fields from the parsed Whois data on a public web page


Disallowed uses include, but are not limited to:

  • Public XML Whois web service
  • Public XML Whois proxy
  • Universal Whois utility that displays parsed data in a standard format

Allowed uses include:

  • Universal Whois utility that shows only raw, unparsed records
  • Domain availability check that only shows registrant name, email address, and expiration date
  • Public service that discovers and monitors expiring domains
  • Internal log file analysis

Two cautions

Domain name registrars and other organizations that maintain Whois servers are very sensitive about the use of the data and their servers. This has important implications:

  1. You should always follow terms and policies listed in the Whois output. Generally, this means that you cannot use Whois data for building a marketing database.
  2. Make arrangements with server owners if you are going to do a lot of queries. If you perform many queries without authorization, they will likely cut you off. For example, as of about a year ago, Network Solutions instituted a flat 1000 query/day/IP address limit. GoDaddy begins eliminating the contact information and dates from Whois output after repeated queries.
