The Whois component allows you to query a WHOIS Server for Domain registration information. 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 is identical to setting the Domain property with the domain that you would like to get information for.
