A domain name can include up to 63 characters before the .COM, .NET, or .ORG ending. You can use numbers, letters, and dashes in your domain but the domain cannot start or end with a hyphen. Domains also cannot contain spaces. Domain names can be worth thousands and thousands of dollars. The more practical and useful it is for others, the more it will be worth.
Domain names can be worth even more in non-monetary terms.
Companies that have spent a great deal of time and money on establishing a corporate identity may find the value of their domain name immeasurable. The worth of a domain name is high, and there is no limit to just how high. I ve decided to register my name in the .COM top level domain. It is a good idea, especially if you are a business. However, if someone else registers these names and a conflict develops, it could cost you thousands of dollars with no guarantee you will be successful.
