What is a domain name? (and how it's different from hosting)

A domain name is the address people type to reach your website — like yourbusiness.com.au. Simple enough on the surface, but a few things about how domains work trip people up, so here’s the full picture in plain English.

What a domain actually is

The internet finds computers using numbers called IP addresses (something like 203.0.113.10). Those are impossible to remember, so domain names exist as friendly labels that point to them. When you type a domain, the internet looks up which server it points to and sends you there.

So a domain on its own doesn’t contain anything — it’s a signpost. It points to a server (your hosting) where your website actually lives. This is the part people most often miss: buying a domain doesn’t give you a website, and it doesn’t give you hosting. It gives you the address.

Domain vs hosting vs website

Three separate things that work together:

• Domain — your address (yourbusiness.com.au). Rented from a registrar, usually yearly.
• Hosting — the server space where your site’s files and email live.
• Website — the actual pages and design you put on the hosting.

If you’re fuzzy on how these fit, what is web hosting lays it out with an analogy.

You don’t “buy” a domain — you register it

Nobody owns a domain outright. You register it for a period (typically one to several years) and keep it as long as you renew. Miss a renewal and it can lapse and be registered by someone else — which is why keeping your registration details current and auto-renew considered is so important.

How the pieces connect: nameservers and DNS

When you have both a domain and hosting, you connect them by pointing the domain’s nameservers (or specific DNS records) at your host. DNS is essentially the address book of the internet — it holds the records that say “this domain’s website is here, its email is there.”

• Point your domain at your host’s nameservers and the host manages the records for you.
• Or keep your nameservers elsewhere and create individual records pointing at your host.

Our DNS setup guide walks through both.

Domain extensions explained

The bit after the dot (.com.au, .com, .au, etc.) is the extension, or TLD. The common ones for Australian businesses:

• .com.au / .net.au — the established Australian business extensions. They require an Australian business identifier (ABN or ACN). Strong signal that you’re a local, legitimate business.
• .au — a newer, shorter Australian namespace (launched 2022), same eligibility rules. Many businesses register both .com.au and .au to protect their brand.
• .com — the global default. Recognisable everywhere, but harder to get a short name and no “local” signal.
• .id.au — for individual Australian residents (personal sites), no ABN needed.
• Plus hundreds of others (.io, .co, .shop, and so on) for specific purposes.

For an Australian business targeting Australian customers, a .com.au or .au is usually the right primary choice. See domain pricing for current rates.

A note on WHOIS (public registration details)

For .au domains, certain registrant details are published in the public WHOIS directory — this is an auDA requirement, not a host’s choice, and there’s no privacy option for .au extensions. For many international extensions (.com, etc.), WHOIS privacy is available. It’s worth knowing before you register.

Choosing a good domain

• Keep it short and easy to say out loud.
• Match it to your business name where you can.
• Avoid hyphens and numbers if possible — they’re hard to dictate.
• Grab the obvious variations (e.g. .com.au and .au) so a competitor doesn’t.

In short

A domain is your address; hosting is where your site lives; DNS is what connects them. You register the domain and renew it to keep it. If you want everything in one place — domain, DNS, hosting, and email — keeping them with one provider makes the connections simpler. You can search and register a domain or ask us if you’re unsure which extension fits your business.
