My EC2 server cannot connect, but the details page shows that the instance is working properly

Question

My EC2 server has been inaccessible for a month due to issues with the Middle East War. The IP address was included with the purchase of the instance and has been in use for over a year. It is not an elastic IP address. Currently, a work order has been issued stating that the normal access time for the instance cannot be determined. As we are an IoT enterprise, all terminal connections are based on the IP of this instance. I would like to ask, how can we purchase a new EC2 server that can use the IPV4 address provided by the old server?

To be honest, I believe you will need to open a support ticket directly within the affected AWS account. As far as I know, there is no manual guide or workaround available without the intervention of AWS Support.

**Technically, AWS does not support the direct migration of a standard public IPv4 address from one instance to another.** Since your address is not an Elastic IP (EIP) but an automatically assigned public IP, it is strictly bound to the lifecycle of the Network Interface (ENI) of the original instance.

*"We release your instance's public IP address when it is stopped, hibernated, or terminated. Your stopped or hibernated instance receives a new public IP address when it is restarted."*

Is this an elastic IP? If so, you can log a support ticket and AWS Support might be able to release it so you could use it in a different region. 
If it's a public IP (that is, not elastic IP). then you probably can't do much.
