You don't necessarily need hosting, it is only needed if you have a website or want to use your domain for email.
Domains and hosting are like cars and registration.
Just like with a car, you register your domain through a registrar or reseller e.g. 123host.au This gives you ownership of the domain for as long as you pay the registration.
Just like a car, if you want to use your domain, you have to park it somewhere. You then have a number of options:
- Park your domain - don't do anything with it, just have it safely looked after
- Redirect your domain - have visitors go directly to another site. You might do this if you have a .com and the same domain, but .au
- Email only - just like it sounds. Full email services but no website
- Website hosting - 123host has hosting to suit your needs
