What Is a Domain Name and How Does It Work?

Your domain name is your address on the internet. Here's everything you need to know about choosing, registering, and managing one.

Your domain name is the single most visible part of your online identity. It's what goes on your business cards, in your email address, and what customers type when they want to find you. Getting it right from the start matters — changing it later is painful. This guide covers everything you need to know before you register a domain for your business.

Everything About Domain Names

What exactly is a domain name?
A domain name is your unique address on the internet — for example, ailacs.com.au. When someone types it into their browser, it directs them to your website. Think of it like a street address for a physical shop: the domain is the address, and the website is the shop itself. Without a domain, your website has no publicly reachable address.
How do I choose a good domain name for my business?
The best domain names share these qualities:
  • Short and memorable — Easier to type, easier to remember
  • Easy to spell — Avoid hyphens, numbers, and unusual spellings
  • Matches your brand — Ideally your business name or a close variation
  • Avoids trademark issues — Check that you're not infringing on another brand
If your ideal domain is taken, try a different extension (.net, .com.au) or add a location or descriptor (e.g., sydneyplumbing.com.au).
Should I get a .com or a .com.au domain?
For Australian businesses, .com.au is usually the better primary choice. Here's why:
  • Google uses it as a signal that you're an Australian business, helping with local search rankings
  • Australian customers recognise and trust it
  • It's less likely to already be taken compared to .com
That said, we recommend registering both the .com.au and the .com version of your domain to protect your brand and redirect traffic from either address to your main site. To register a .com.au domain, you must have an Australian Business Number (ABN).
How much does a domain name cost in Australia?
Standard domain registrations are surprisingly affordable:
  • .com.au: ~$15–$25/year
  • .com: ~$15–$20/year
  • .net.au / .org.au: ~$15–$25/year
Premium or previously owned domains (ones with existing traffic or desirable keywords) can sell for hundreds or thousands of dollars. Always register your domain yourself or make sure it's in your name — not your web developer's account.
What is the difference between a domain name and web hosting?
These two things are often confused but are completely separate:
  • Domain name = Your address (e.g., mybusiness.com.au)
  • Web hosting = The server where your website files are stored
You need both. The domain tells people where to go; the hosting is what they actually arrive at. You can buy them from the same provider or different providers — it doesn't matter as long as the DNS is pointed correctly.
What is DNS and why does it matter?
DNS stands for Domain Name System — it's essentially the internet's phone book. When someone types your domain into a browser, DNS translates that human-friendly name (mybusiness.com.au) into a numeric IP address (like 104.21.45.32) so the browser knows which server to connect to. DNS also controls where your business emails are delivered. Getting DNS settings wrong can take your website or email offline — which is why we always handle DNS configuration for our clients as part of setup.
Can I change my domain name later?
Technically yes, but it's painful and risky. Changing your domain means:
  • Updating every link to your site from other websites
  • Updating all your Google Business, social media, and directory listings
  • Potentially losing SEO authority built up over years
  • Redirecting old domain traffic indefinitely to avoid losing visitors
Choose your domain carefully the first time. If you're unsure, talk to us before you register — it's a five-minute conversation that could save you years of headaches.
