This address is decoded by reading from right to left.
The au in the domain name indicates this is an Australian Internet site. The Net uses standard country codes:
|None||USA or Global|
The com part of the address designates example-site-name as a commercial or business organisation. This is also part of an international standard.
|mil||Military Defence Forces|
|org||Non-Profit or Community Groups|
