Where can I find the client IP address of a request connecting to my app?

App Platform adds a do-connecting-ip HTTP header that contains the client’s IP address for requests directed to your app. While the x-forwarded-for header is often used for this purpose, App Platform uses this header for the IP address of the DigitalOcean ingress server that forwarded the request to your app.

You cannot create Droplets with a specific IP address, but you can use reserved IPs for a static address that you can migrate between Droplets.
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.
Add the root domain to the list of domains in the app’s settings along with the wildcard subdomain.
