What Are Domains?

Domains enable you to create public endpoints with hostnames matching the domain. For example, after you create the domain your-name.ngrok.app, you may create the Endpoint https://your-name.ngrok.app.

Valid Domain names include:

• ngrok-managed domains, like foo.ngrok.app.
• Your own custom domains, like example.your-domain.com, by creating a CNAME DNS record with your domain's DNS provider.

Configuration

Domains also enable you to configure other domain-level behaviors, including:

• Global Load Balancer configuration - Choose which points of presence handle traffic to a Domain's matching endpoints.
  Coming Soon

  Per-region global load balancer configuration is coming soon, request access to the developer preview.

• TLS Certificate management - Configure automatic certificate provisioning or select a certificate you uploaded yourself.
• Dedicated IP address configuration - Attach static, dedicated IPs for a Domain's matching endpoints receive traffic on.

You can manage Domains on your ngrok Dashboard or via the ngrok API.

Ownership

Your account exclusively owns its Domains and all of their nested subdomains within ngrok. That means:

• No account may create a Domain with a name that is a subdomain of your Domains.
• No other account may create endpoints with a hostname matching your Domain or any of its nested subdomains.

For example, if you create a Domain with the name foo.ngrok.app:

• No other account create the Domains foo.ngrok.app or bar.foo.ngrok.app.
• No other account may create the endpoints https://foo.ngrok.app or https://bar.foo.ngrok.app.

API

Domains are programatically managed via:

• /reserved_domains API Resource
