Custom domains

To put your app on your project’s custom domain name, use the CDN service.

This supports IPv6.

For all custom domains, we recommend incorporating HTTPS-Only Standard guidance, including HSTS and preloading.

If your application requires DNSSEC, you are responsible for ensuring your custom domain is DNSSEC-enabled before following these instructions.

For context, Cloud Foundry’s Routes and Domains documentation explains the overall model and terminology that uses.
