1. You will need to own a domain name and have access to its DNS settings. If you want to purchase a domain, you can go here: https://d.pr/QJrI8c. If you already own one, you will need to add it into Instapage and go into your domain registrar’s DNS settings and create a new CNAME record.
You can find the step-by-step instructions for creating a CNAME record and pointing it to our server address as seen here: https://d.pr/QZoyvs
NOTE: You do not need to create any other type of record in order to publish on Instapage. You cannot use an A record or any other type of record besides a CNAME. Even if the instructions provided by the domain registrar contradict this, you can only publish using a CNAME record that points to secure.pageserve.co. It is not possible to publish using an IP address or any other method. As long as you do not have other records with the same name, you will be able to create a CNAME and point it to secure.pageserve.co regardless of other settings in your DNS.
2. After you have done that, you will need to add your new subdomain to the Domains section of your Instapage workspace, by following the instructions here: https://d.pr/x1u6c2
3. Go to the page you want to publish, click on Publish page in the slideout, then click on Custom Domain, select your URL from the dropdown, and publish the page.
