What characters can be used in a domain name?
You can use letters, numbers and the hyphen "-" in a domain name. Unfortunately, special characters like, "_!@#$%^&*," are not allowed. You will be alerted if you have included any invalid characters in your domain name before you register. Domain names cannot contain spaces or begin or end with a hyphen. Domain names are NOT case-sensitive. The domain name goprohosting.com is treated the same as GoProHosting.Com.
