What type of public IP should be created to ensure consistency in an OCI web server's address after redeployment?

Creating a reserved public IP and associating it with the Virtual Network Interface Card (VNIC) of an OCI web server ensures that the web server retains the same public IP address even after it undergoes redeployment.

Reserved public IPs are not tied to a specific instance lifecycle, meaning that they persist independently of instance states such as stop/start or termination. When you reserve a public IP, you essentially secure that address for your use, which is critical for services where consistent public access is essential, such as web servers.

Additionally, associating the reserved public IP with the VNIC allows you to maintain control over the IP attached to your specific compute instance. This ensures that once the instance is deployed again or modified, the public IP remains the same, preserving any bookmarks or DNS configurations pointing to that address.

In contrast, a temporary public IP would be released when the instance is stopped or terminated, making it unsuitable for applications needing a consistent public address. Associating a reserved public IP with the subnet would not achieve the same level of specificity and would not guarantee that the IP is linked directly to the intended VNIC. An ephemeral public IP would also not suffice as it is temporary and is released once an instance is terminated, ultimately leading to changes
