Learn how to use your own custom domain (instead of *

A domain name is the address that visitors use to access the site. If you want to get rid of the url (which is automatically assigned when you start a trial site) and use your own unique domain name rather than the default URL, you can simlpy register one and set it up with your site.

The workflow for assigning a custom domain name of your site consists of the following steps:

Step 1 - Buy and register a domain name

If not already done, purchase and register a domain name with a domain registrar. For more information, see How to Register Your Own Domain Name by Christopher Heng on

Step 2 - Add a custom domain to your Business Catalyst website

Once you've purchased the domain, it's time to add it to your site.

Step 1. Login to Admin Panel.

Step 2. Go to Site Settings > Site Domains.

Step 3. Click New Domain.

Step 4. Enter your domain name in its plain format (without http://www). Example:

Note: This step assumes you have previously selected to Use this service to host your website

After adding a domain name to your Business Catalyst site, the confirmation message above will display our namservers and corresponding IP addresses. You now only need to point the domain name to these DNS servers from the console provided by your registrar. This is also known as redelegating the domain name:

  1. Log in to your domain registrar's control panel.

    Use the login name and password that you created when you registered the domain name.

  2. Look for the option to set or change name servers.

    The workspace for managing domain name servers (or DNS) is different for each registrar. See the registrar website or contact the registrar for help.

  3. Replace any existing name servers with the following business catalyst name servers:
    • -
    • -
