What is a domain?

A domain name is your website address on the internet and gives you an online identity or brand. It’s a valuable part of your business identity and is an important marketing tool that can help customers find and identify with your business.

A domain usually looks like this:


The components of a URL (website address) are:

  • http:// – this is code and means that it is an address on the internet. This is used by various software. For example, your email client will know when you click on a link with http:// to open up your web browser and go to that link.
  • https:// – the “s” means it has “SSL” installed. This encrypts the data between the server (website) and the end user’s browser. This is best practice for all websites.
  • www – this is used on some domains for technical reasons. Although used widely in the “old days”, most websites do not use www anymore.
  • customname – this is your custom name that you choose.
  • com – this is the domain (Top Level Domain)



Domains represent a country, organisation or organisation type. There are many different domains (see this list). Many domains have rules and restrictions and cannot be used while some have very few restrictions.

  • .net    .com   .org are the easiest to register
  • .com.au are for Australian brands and organisations. There are more Australian domains available.
  • .org.au  requires a registered organisation

To buy an Australian Domain (.com.au)you will need your business ABN or ACN to purchase a domain name (although you can register with someone else ABN/ACN)
Australian domains are managed by .auda
