Public IP of test environment - Whitelisting

Hello

For the purpose of whitelisting, our middleware, has requested the IP used by one of our test environments https://<instance_name>.test.fs.ocs.oraclecloud.com/.

After receiving feedback from said middleware, we found out the IP that was used during the call by our test environment.

However, after checking the relevant Oracle documentation https://docs.oracle.com/en-us/iaas/tools/public_ip_ranges.json, this specific IP is not included in the list for eu-frankfurt.

Could you please clarify the above findings?

Also, can you please specify if this IP is static?

Thank you.
