I have a long list of domains .com, .net, .org and .es and I need an application to determine if they are registered or not.
To check a domain .com, .net, .org there are many sites like [login to view URL] , [login to view URL]
To check .es you have to go to <[login to view URL]> and enter the domain where it says "Busca", if the domain is available, it should appear the text "Nombre de Dominio inexistente"
These are suggested sites, you can use any site to check whether the domains are available or not.
Application should be multithreaded and very fast.
