What is the difference between hostname and IP address for SSL configuration?

Using the hostname is generally preferred for SSL configuration because it allows the client to resolve the server's address. However, if the hostname changes, the client will fail to connect. Using the IP address ensures a stable connection regardless of hostname changes. You can specify either the hostname or the IP address in the DSN settings, but using the IP address is more reliable for production environments. Consider using a fully qualified domain name (FQDN) to avoid DNS issues.
