The three most commonly used domain name extensions or top-level domains include but are not limited to .com, .net, and .org. All of these top-level domains are widely accessible on the Internet to anyone without any restrictions. Other top-level domains can have restrictions and will not allow just anyone browsing the Internet to access them.

The top-level domain names such as .com, and .net are most widely used and recognized. The .org extension was originally intended for non-profit and there has been some discussion at ICANN about restricting these top-level domain names to only legit non-profit businesses. The .org is a special top-level domain and also has its own regulations for transferring domain names, which can be a complicated process.

These top-level domains have become very popular and to keep up with the growing demand for top-level domains ICANN has created 7 new types of top-level domains.

Before selecting a domain name or top-level domain make sure to choose the proper category that your business falls under and ONLY allow an accredited registrar to register your domain. Be sure to select a good domain name that represents your business properly. Keep in mind that your domain name and top-level domain are very important when it comes to web site visibility on the Internet.
