Why does my app have a US-based IP address when I created it in a different region?

In App Platform, the application is located in the region where you create the app in. However, App Platform uses the Cloudflare CDN, headquartered in the US, to provide domain configurations for apps. This means that when you lookup the IP of your app, you are seeing the IP address of the CDN’s load balancer and Anycast network. This does not mean your traffic is being routed through the US, though.

To check the IP address of your app, you can run the following from within the app’s console:

dig +short myip.opendns.com @resolver1.opendns.com

The IP output is the dynamic public IP address of your app. Unlike a static IP address, this address can change.

Why can't I route traffic to my app's dedicated egress IP address?

Dedicated egress IPs route egress (outbound) traffic from an app. To route ingress (inbound) traffic to an app, use one of App Platform’s public ingress IPs.

Why doesn't my app's wildcard subdomain work?

Why is my app not resolving .gov domains?

App Platform apps may be slow or unable to resolve .gov domains because the domain administrators have blocked DigitalOcean’s IP addresses. To fix this, you can contact the domain administrator or use a custom DNS resolver.
