Use a custom hostname to serve CDN content from your own domain instead of the default bunny.net URL.
1

Add the hostname to your pull zone

  1. Open your pull zone in the dashboard
  2. Locate the Hostnames panel in the General section
  3. Enter your custom domain (e.g., cdn.yourdomain.com)
  4. Click Add hostname
Add custom hostname
The hostname appears in the Linked Hostnames list.
2

Copy the CNAME record

Copy the CNAME record value shown below the hostname field. You’ll need this for the next step.
Copy custom hostname CNAME
3

Update your DNS settings

Add a CNAME record at your DNS provider:
  1. Log in to your DNS provider (Cloudflare, Route 53, or similar)
  2. Create a new CNAME record:
    • Name/Host: Your subdomain (e.g., cdn)
    • Type: CNAME
    • Value: The CNAME from step 2 (e.g., yourzone.b-cdn.net)
    • TTL: 3600 seconds or lower
On Cloudflare, disable the proxy option (orange cloud icon). Proxying interferes with DNS resolution and prevents your custom domain from working with bunny.net.
4

Wait for DNS propagation

Save the DNS record. Your domain connects to bunny.net once DNS propagates, typically within a few minutes to an hour.
5

Enable SSL

Click Verify & Activate SSL to get a free Let’s Encrypt certificate for your custom hostname.
Verify and activate SSL
If you skip SSL verification initially, find your hostname in the Linked Hostnames section and click Enable to activate a free certificate or upload your own.

Root domains

CNAME records cannot be created at the apex level (yourdomain.com) per the DNS specification. Most DNS providers don’t support non-standard record types like ALIAS or ANAME that work around this limitation.
Pull Zones do not support direct IP address connections. There is no stable anycast IP that can be used with A records to point a domain to a Pull Zone. You can use a direct IP as the origin with a custom Host header, but pointing an A record to a specific Bunny IP is not supported. See How to set up a direct IP origin URL for more information.
To use a root domain with your Pull Zone, you have two options:
  1. Use Bunny DNS (recommended): Bunny DNS supports CNAME flattening on apex domains, allowing you to point your root domain directly to a Pull Zone. See CDN Acceleration for setup instructions.
  2. Redirect apex to www: Create a CNAME for www.yourdomain.com pointing to your Pull Zone, then set up an HTTP redirect from your root domain to www.
