A domain name can be up to 63 characters (letters, numbers or combination) long plus the characters used to identify the domain extension (.com, .net, .org). The only symbol character domain names can include is a hyphen (-) although the domain name cannot start or end with a hyphen nor have consecutive hyphens. Symbols such as asterisks (*), under scores (_), and exclamation points (!) are not permitted.
