There are a number of companies that offer free web space. You can have a redirect service point your domain name to one of those sites. When Web surfers type your custom domain name into their Web browsers, the redirection service automatically forwards them to your existing home page, no matter where it's located or what its actual URL is. If you change the location of your page, you can simply notify your redirection service and they will forward to your new location.
Redirect services offer minimal expense, flexibility, and convenience.
Most of them charge an initial fee to set up your account and a small annual fee, although some provide their services free. Some common redirect services can also help you register for a domain name.
