Whois Component

Properties Methods Events Configuration Settings Errors

The Whois component allows you to query a WHOIS Server for Domain registration information.

Syntax

nsoftware.IPWorks.Whois

Remarks

This component implements the WHOIS protocol defined in RFC 954.

To use the component, simply call the Query method and set the Domain parameter to the domain you wish to retrieve information for. This will trigger a WHOIS search on the domain. Upon completion of the search, the DomainInfo property contains the information about the domain.

If the Server property is empty, then a search is performed automatically at "whois.internic.net" for the appropriate WHOIS server for the domain, and the Server property is set to the server found.
