The first part, which is optional, is the "www" seen in many addresses. After the "www" comes a dot and then the domain name, often chosen to draw people to the site or promote a company. The extension is the last part of the main Web address and is always preceded by a dot.

Common Extensions

The most common Web address extension in the world is .com (said "dot com" when spoken) This indicates a commercial website. The extensions .net, .gov and .info are also popular.
Rules for Extensions
-
You are not required to pick a particular extension, so commercial organizations will sometimes choose something other than .com. However, some countries limit users' ability to purchase country extensions to people living or doing business in their country.
Why Choose Unusual Extensions
-
Sometimes, individuals choose a more unusual Web extension, sometimes because the .com for their domain name is already taken and sometimes just because they want to emphasize some other aspect of their domain than business.
