Q. What types of characters can be used in domain names ?

Ans: A site domain will contain numbers (0-9), letters (a-z) or hyphen (-). a site domain cannot begin or end with the hyphen (-) nor they’ll be in consecutive order. Empty area are not allowed within the domain name. Domain names should be a minimum of 3 and at the most 63 characters long. a site domain name isn’t case-sensitive, therefore you’ll be able to use upper or lowercase letters when using your new domain.
