Constructor for the object instance.

function WhoIs(const ADomain: string): string;

String - Results from the WhoIs server.

WhoIs is a String function that queries the WhoIs server using the query value specified in the ADomain argument. Assign values to the Host and Port properties for the appropriate server before calling this method.

WhoIs calls Connect to open the connection to the WhoIs server identified in Host and Port, and writes the query in ADomain to the WhoIs server. WhoIs reads pending resuilts using the AllData method prior to calling Disconnect.
