Domain names, explained for business owners

Domains are one of the most confusing bits of having a website, and one of the most important to get right. Get it wrong and you can lose your web address, your email, or both.

Let's clear it up in plain terms, then cover the Australian rules and the traps that catch people out.

Domain, hosting and email are three different things

Think of it like a shop. The domain is your street address, the part people type in, like yourbusiness.com.au. Hosting is the actual shop building where your website lives. Email is your phone line.

They're often sold together, so people assume they're one thing. They're not. You can move your website to new hosting and keep the same domain, just like changing the fit-out without changing the address.

Understanding they're separate is what stops you getting locked in or losing access later.

.com.au and the ABN rule

To register a .com.au domain you need an Australian presence, normally an ABN or ACN. That's the rule, and it's actually a good thing.

It means not just anyone overseas can grab a .com.au, and it signals to customers that you're a real Australian business.

A .com.au tends to build more trust with local customers than a plain .com. For a local service business, it's usually the one to get.

It must be registered in YOUR name

This is the big one. Your domain must be registered with you, or your business, listed as the owner. Not your web guy, not the agency, not a mate who set it up.

If someone else is the registered owner, they control your address. If you fall out with them, or they disappear, you can be locked out of your own domain and email. It happens more than it should.

Ask any provider directly: is the domain registered in my name, and can I log in to the registrar to prove it? If the answer is fuzzy, push until it isn't.

Renewal traps

Domains are rented, not owned. You pay to hold one for a year or two, then you renew. Forget to renew and you can lose it.

Watch for renewal notices going to an old email address, and for cheap first-year deals that jump to a high price on renewal. Some dodgy operators also send official-looking "renewal" letters for domains you don't even hold, hoping you'll pay.

Set your domain to auto-renew if you can, and keep the contact email current. Know who your registrar is and how to log in.

What happens when a domain lapses

First your site and email stop working. There's usually a short grace period where you can still renew and get it back, so act fast if it happens.

Miss that window and the domain is released. Anyone can register it. Sometimes that's a competitor, sometimes it's someone who'll try to sell it back to you for a fortune.

The whole mess is avoidable. Know your renewal date, keep ownership in your name, and check your details once a year. Ten minutes now saves a very bad week later.
