Domain names and redirecting

hello fellow kirupians

I am about to buy a domain name (which is unregistered yet thanks god for my money :beam: ) but I’m a little confused:

This is of course assuming whoever sells the domain allows for redirection.

I’ve looked around a bit but I get really confused as most sites just display charts and prices and packages but don’t explain the whole deal that well.

If you can shed some light on the matter, I’d be grateful !

cheers and good day :pleased:
