What is allowed in a domain name?
The only characters allowed in a domain name are the 26 letters of the English alphabet, numbers 0-9, and hyphens (-). A domain cannot begin or end with a hyphen, but it may contain one or more hyphens. You may use up to 63 characters plus the gTLD (generic Top Level Domain such as .com, .net, and .org) as part of the domain name. Domain names are not case sensitive and are usually displayed in all lowercase. You may, however, use capital letters to emphasis words in your domain name, like: JoesHardware.
