Pragmatic Technologies for Life and Business Success®
When registering your domain name (URL) the one I recommend you secure, that is the most important and popular, is the one that ends with a .com extension. Assuming then that you have secured the .com extension, you are in great shape. However, you may want to also consider registering the following extensions: .net, .org, ,info, .biz and .us if you are in the US.
For example, my blog name is hosted under www.ChadBarr.com which is registered and owned by me. What if someone decides to register one or all of the other extensions, such as the .net which would then make www.ChadBarr.net available for them to populate with their content. This could and would create a situation that when my clients search for me, they would most likely find the other domains that are actually not associated with me and my company.
So the primary reason you want to consider this, is to avoid others from trying to take advantage of your success and then registering and owning the other domains associated with your company name or brand names.
One final point of consideration is that once you have registered and own all these extensions (URLs) is to redirect all of them to your .com domain so when one tries to type the others, they will end up on your main domain.
