The issue
I'm considering accessing other resources from Cloud9.
On the other resource side, I want to restrict the source IP addresses, but Cloud9's public IP address changes every time it starts up.
Please tell me how to set a fixed public IP address for Cloud9.
The solution
It is possible to set a fixed public IP address for Cloud9 by assigning an Elastic IP address to the EC2 instance of the Cloud9 environment.
Share a running application over the internet - AWS Cloud9
Your application's public IP address might change anytime the instance for your application restarts. To prevent your IP address from changing, allocate an Elastic IP address. Then, assign that address to the running instance.
