AWS App Runner Static IP Addresses

Question

Does App Runner support static IP addresses? I should send requests from my application (abcdefg.eu-central-1.awsapprunner.com) to a third-party webservice that filters IPs through a firewall. The domain of my application (abcdefg.eu-central-1.awsapprunner.com) resolves into 3 different IPs and they appear not to be static.

Hello.

Do you want to fix the IP address for outbound communication from AppRunner?  
If you want to keep the IP address fixed for outbound communication, you can do so by connecting AppRunner to a custom VPC and accessing third-party web services via NAT Gateway.  
In other words, the IP address you allow in the third-party web service will be the IP address of your NAT Gateway.
