Enable Bunny DNS and CDN Acceleration

Migrate your domain to Bunny DNS and enable CDN Acceleration. This is a prerequisite for the Bunny Offloader and Bunny Shield features in the WordPress plugin.

Several features of the bunny.net WordPress plugin, including Bunny Offloader and Bunny Shield, require that your domain uses Bunny DNS with CDN Acceleration enabled. Traffic must flow through the bunny.net CDN proxy so the plugin can offload media to Storage and so Shield can inspect and mitigate requests at the edge.

This guide walks through migrating your domain to Bunny DNS, enabling CDN Acceleration, and verifying that everything is wired up correctly. Once complete, head to Enable Offloader or Enable Shield to turn on the features themselves.

These features are only supported when using the official bunny.net plugin and managing DNS through bunny.net. They are not compatible with third-party plugins or external DNS providers.

Prerequisites

• A bunny.net account
• Access to manage your domain’s DNS settings

Step 1: Migrate your domain to Bunny DNS

Skip this step if your domain is already using Bunny DNS.

1. Add a DNS zone

   Log in to bunny.net and go to Delivery → DNS → Add DNS Zone. Enter your domain name and click Add DNS Zone.

2. Add your DNS records

   Follow the setup instructions, then click Okay, I’m done. Click Add Record, enter the required details, and continue adding records as needed.

3. Verify propagation

   Confirm your DNS settings have propagated using the bunny DNS Lookup Tool. Look for NS records pointing to kiki.bunny.net or coco.bunny.net.

When creating a DNS zone, it must be based on the root domain (e.g., domain.com). Creating a zone for www.domain.com or something.domain.com is not valid.

When migrating your DNS, make sure to transfer all existing DNS records, not just the website-related ones. Failing to do so can result in critical services (like email) going offline.

Step 2: Enable CDN Acceleration in the plugin

If your domain was already using Bunny DNS when you installed the plugin, the “Enable CDN Acceleration” option may not appear. Skip to Step 3 to check if it’s already enabled. If not, you can reset the plugin to start the configuration from scratch.

1. Enable CDN Proxy on DNS records

   In the bunny.net dashboard, go to the DNS section. Click the button in the CDN Proxy (or CDN acceleration) column next to each DNS record.

   
2. Enable in the WordPress plugin

   In your WordPress Admin Panel, navigate to bunny.net → Offloader or bunny.net → Shield. Follow the on-screen prompts and click Enable CDN Acceleration (or Enable Bunny DNS from the Shield tab). You’ll receive an orange confirmation message once configured.

   

Enabling CDN acceleration disconnects your current Pull Zone and creates a new one. Make sure to copy any essential settings (Edge Rules, Cache settings, Optimizer configurations) from the old zone to the new one. The old Pull Zone can be safely deleted after migration.

Step 3: Confirm CDN Acceleration is working

Verify your setup using any of these methods:

• In the bunny.net DNS section, a green CDN Proxy icon next to your DNS record indicates proper CDN integration.

• Inspect response headers from your site. Look for:
  • CDN-ProxyVer: 1.04
  • CDN-RequestPullSuccess: True
  • CDN-RequestPullCode: 200
• In your WordPress Admin Panel, go to bunny.net → About. Under Technical Information, check the Request Headers section. If you see both Cdn-RequestId and Via: BunnyCDN, everything is working.
