I am trying to create an application (Language C++ using .NET 2.0) which allows users to get information about a domain, for example if the domain is free or it is used, update date, creation date, expiration date etc.
I know about some services which do that like whois.domaintools, whois etc. Now I want to know how they work and how I can write an application which will collect the same information without using any service. Can anybody help me?
