Free Domain Name - Domains can contain between 1 and 63 characters not including the .com, .net, .org etc extensions The letters A to Z, the digits 0 to 9 and the dash "-" are allowed. The dash cannot be the first or last character. The letters are not case sensitive so for example FineE.com, FINEE.COM, finee.com etc are all the same domain. When a domain is used the letters may be entered in lower or upper case.
