built 622 days ago
WhoisClient.dll is a .NET component for domain names whois searches. You can integrate Whois searches with your application using any .NET language. WhoisClient.dll was written entirely in managed code. It can perform recursive whois queries and automatically finds the correct whois server.

Internationalization: The WHOIS protocol was not written with an international audience in mind. A WHOIS server cannot tell which text encoding it is using for either the requests or replies, and the servers were originally all simply using US-ASCII, although this cannot be assumed anymore with international servers. This obviously will impact the usability of the WHOIS protocol in countries outside the USA, especially as internationalized domain names are falling into wider use. A user can (and possibly will have to due to this limitation) use punycode, but this leads to conversion problems as the punycode system is not easy for a regular user to grasp.

A WHOIS client makes a text request to the WHOIS server, then the WHOIS server replies with text content. All requests are terminated with ASCII CR and then ASCII LF. The response might contain more than one line of text, so the presence of ASCII CR or ASCII LF characters does not indicate the end of the response. The WHOIS server closes its connection as soon as the output is finished. The closed connection is the indication to the client that the response has been received.

Early WHOIS servers were highly permissive and would allow wild-card searches. You could do a WHOIS lookup on a person's last name and get all the individual people who had a registered handle. You could do a query on a keyword and see all registered domains containing that keyword. You could even query a given administrative contact and see all domains they were associated with. Due to the advent of the commercialized Internet, multiple registrars and unethical spammers, such permissive searching is no longer available.

With the new shared registration system model, the nature of the WHOIS server has changed. Traditionally, the InterNIC maintained the WHOIS server for .com, .net and .org domain names, and a single query returned full whois data including registrant, administrative contact, billing contact, technical contact, and nameserver information. Under the new system, the registry WHOIS simply contains information on which Registrar is authoritative for a given domain. Click here for details.
