Registering all possible Domain Extensions

[abirami]

Is it advisable to buy all the possible domain name extensions for a domain? For example, If i have website with .com.au and its already branded, should I also buy .com, .net, .org, .info etc inorder to avoid others misusing the brand name?

Thanks in advance.

If you are selling outside of Australia then it should be worth having the .com as well as the .au

If you can get them all, definitely! Usually if you find a .com available, the others are too. If I buy a domain today that I think is going to become a premium domain, I'm going to get the .net and .org by default, that is a given.

We may use the .net as a development site and redirect .org to .com and never promote anything but the primary domain. There are exceptions of course.

Definitely a good idea to register the other extensions and 301 redirect them to your extension of choice especially if it is a big company site. However, if you are a domainer with hundreds and hundreds of domains like me then choose wisely which ones you want to buy multiple extensions for.
