What makes up a valid domain
name?
The only valid characters for a domain name are letters, numbers
and a hyphen "-". Hyphens may be anywhere in the middle of a name,
but can not be located at the end or beginning of a name. A valid
domain name does not have spaces. A domain name can be up to 67
characters long -- including the 4 characters used to identify
the Top Level Domain (.com, net, .org). Do not type the www. or
your ext. before your domain name when registering as it is automatically
inserted.
