What is domain name forwarding?
Domain forwarding is similar to when a web page redirects a visitor to another website, but instead of using HTML or a script to do the redirection, the domain name itself redirects to the website. When a domain is set to forward visitors to another website, the domain name does not stay in the web browser's URL bar.
Why/when would I use domain forwarding?
You would use domain forwarding to point a custom domain to a non-custom domain. If you launch your site with a non-custom domain and later choose a custom domain, you can use domain forwarding for this case.
How do I forward my domain name?
Forwarding your domain name would be done at your domain registrar. Contact your domain registrar's support for assistance.
