Preview DNS lets you test your website prior to launch to ensure it displays and behaves properly on our hosting servers before modifying your domain's DNS record. This is beneficial when you are setting up a website for a domain that is currently active, either in your account or with another hosting provider.
Before your DNS settings are modified to point to our hosting servers, you must upload content using your hosting account IP address and not your domain name. You can find the IP address of your hosting account in the Hosting Control Panel's summary page. Once your domain's DNS settings have been modified, you should upload content using your domain name, as your account's IP address may change.
