Your domain name is the address of your website, but better, it’s also the directions to your website. Hosting is the physical location. Your domain tells the browser how to get to that location and connects to your website.
So when you type your domain name into a browser, the internet uses your domain name to find your website and send the visitor over to your site. A typical URL (web address) looks like this (www.example.com) made up of 3 parts. (www).(your-business-name).(extension) Most important are the .your-business-name and the .extension.
The domain name for this website is www.dotupp.com
You will need to choose a .domain-name and the extension for your website. Typically the extension for Australia is (.com.au) or Globally the extension (.com, .net). If your business only serves customers in Australia then a .com.au is preferred. Otherwise use a global name extension.
Note: .com.au domain names require an ABN (Australian Business Number)
