Registering special/non-standard domain for your app (.online .club)


This is not a direct Meteor questions, but I was planning to register a special/non-standard domain name for my Meteor app, cause something like .online or .club would describe my application quite well. However, I could not open a single .online or .club web sites and browser bounced a message that page does not exist. I would assume that or or or would exist?

What is the case? Will I get a zombie domain that cannot be used for my web page if I registered something with .club or .online? Or is this something that I must configure on my linux server, most likely I do know shit about DNS.
