CNAME & SSL

Learn how to add and configure a CNAME to map your custom domain and enable secure HTTPS delivery.

A CNAME record (Canonical Name record) allows you to associate your custom domain — for example, cdn.yourdomain.com — with the default hostname provided by Medianova, such as yourzonename.mncdn.com.

Using a CNAME provides consistent brand identity, simplifies DNS management, and enables secure HTTPS delivery through the Medianova Control Panel.

Add a CNAME

1

Open your CDN Resource

From the left menu, go to CDN → CDN Resources, and click the resource for which you want to add a CNAME.

2

Access the CNAME & SSL tab

Select the CNAME & SSL tab from the horizontal navigation menu. The CNAME input field appears at the top of the tab.

CNAME

3

Enter the CNAME value

Type your custom domain (for example, cdn.yourdomain.com) in the input field and click Submit. The CNAME is saved and applied to your selected CDN Resource.

4

Create the DNS mapping

In your DNS provider’s management panel, create a CNAME record that points your custom domain to the Medianova CDN hostname.

Example:

cdn.yourdomain.com  CNAME  yourzonename.mncdn.com

After DNS propagation, requests to your domain will resolve through Medianova’s CDN edge network.

Configure SSL & TLS

1

Select an SSL certificate.

In the SSL Certificate section, choose one of the available options from the Select SSL Certificate dropdown:

• Shared SSL – Use Medianova’s shared certificate.

• SNI – Use your organization’s uploaded certificate.

• Custom SNI – Apply a specific SSL from your list.

• Disabled – Turn off HTTPS for the resource.

2

Apply the changes.

Click Submit to save the configuration. The selected SSL certificate will secure all CNAMEs assigned to this resource.

3

Configure TLS versions.

At the bottom of the tab, enable supported TLS versions (recommended: TLS 1.2 and TLS 1.3). Click Submit to confirm.

For detailed SSL & TLS configuration instructions, see SSL & TLS Encryption.

Verification and Troubleshooting

• DNS propagation may take several minutes depending on your DNS provider’s TTL configuration.

• CNAMEs must be unique and not used by any other services (for example, mail or web hosting).

• If you are using a Custom SSL, ensure the certificate covers all configured CNAMEs (via CN or SAN fields).

• TLS 1.1 is deprecated and should remain disabled for security compliance.

• To verify your configuration, run:

  nslookup cdn.yourdomain.com

  The response should resolve to your Medianova CDN hostname.

Example (HTML Integration)

When your CNAME configuration is active, you can replace original URLs in your web assets with the CDN domain:

<!-- Origin URL -->
<img src="http://yourdomain.com/images/logo.jpg" alt="">

<!-- CDN URL -->
<img src="http://cdn.yourdomain.com/images/logo.jpg" alt="">

Your CNAME domain (for example, cdn.yourdomain.com) now resolves to Medianova’s edge network, serving cached content from your CDN Resource.

Your CDN Resource is now accessible through your custom domain (for example, cdn.yourdomain.com). All requests to this domain are served securely via Medianova’s edge network using the configured SSL and TLS versions.
