Publisher review:Active WhoIs will enable any .NET developer to query a WhoIs server to check both the availability and information related to any second-level domain name (.COM, .DE, .SE, …). This WhoIs component will enable any .NET developer to query a WhoIs server to check both the availability and information related to any second-level domain name (.COM, .DE, .SE, …).
You can also do a Global WhoIs search that will query all specified WhoIs servers and return a collection of results with all the information you need to display or manage.
Our component provides default WhoIs servers for each top-level domain (up to 67) and includes logic to detect the availability of those servers. You can also define your own WhoIs server list using an external XML definition file or simply add them using code in the Servers collection.
This component is the ideal solution for an ISP or registrar that wants to provide a WhoIs gateway for their customers. The component's ability to work asynchronously makes it ideal for your Windows or web applications. Full source code is available.
