What is domain parking?
Domain parking lets you cheaply reserve a domain name for future use and display an "under construction" default page on it. You can register a domain and not park it anywhere but then your site will be simply inaccessible until you get a web host. Some registrar let you park your domain for free.
hostripples.in will park your domain with a message 'Under Construction', free of cost. Later you can direct it to your web server.
