WhoisCL is a very simple and basic web utility that runs from the Windows console (that is, from MSDOS) and provides you with all the detailed information of the registration of each website that you indicate.
So in a direct and very fast way you get thanks to WhoisCL who owns the registration of each website that we are interested in: name, address, city, email, telephone, expiration date of said registration, etc.
WhoisCL thus becomes a tool that every webmaster or web programmer should use quite regularly, in order to keep up with the records for which he is most interested.
You can free download WhoisCL 32, 64 bit and safe install the latest trial or new full version for Windows 10 from the official site.
