In this Whois lookup project using ASP.net 2.0 you will see how to lookup for .com , .info, .in, .ac,.800,.af,.al, .art, .mobi, .br and more
domains using TcpClient and port 43

The buety of this who is look up is you can add new extensions in to Patterns.XML file and server name where to lookup. There is no thridparty DLl

e.g.

<ServerList>
<Extension>.*\w\.?\w\.com</Extension>
<!--<WhoisServer>whois.verisign-grs</WhoisServer>-->
<WhoisServer>rs.internic.net</WhoisServer>
<!--<WhoisServer>whois.internic.net</WhoisServer>-->
</ServerList>

Here in notde Extension, .Com is extensions and rs.internic.net is registerer where we our system is going to query (lookup).
If system unable to get info from that server. "rs.internic.net" will provide info of where it is registererd and system will query that location.

Feel free to discuss on it,
