What is Domain Name System and why it is important?

The domain name is used to identify one or more IP addresses. For example, the domain name microsoft.com represents a dozen IP addresses. The domain name is used in the URL to identify specific web pages. 

How do I buy a unique as well as keyword type and price of a domain name in Australia?

Find and register the available domain names in Australia for your immediate or future use. Enter your web domain name search in the tool below and select an extension; for

example .com.au, .net.au, .com, etc., then click on "Check 

Availability". Australian domain names (.com.au & .net.au) can be registered for a period of $ 30 per year. Whereas most global domain names (.com, .org and .net) can be registered to start from $ 15 per year and up to $ 30. All renewal and transfer prices are equal to current registration prices. The domain transfer cost is almost the same as the renewal cost. 

Why we have to buy Australian Domain (.com.au) instead of .com extension type domain.

First of all .com, .com.au or .in all Extension type domain is visible in all over the world but search engine optimize their website according to relevancy like when searching from India then .com and .in appear most on the top page. Similarly when we searching from Australia then .com.au and .com type domains comes with priority high. 

If you are targeting the Australian customer as well as searching domain provider in Australia then Aussie Webhost, Broadway Infotech and Digital Host, etc. are the top well-known company in Australia.
