Which port is commonly used by SSH on an alternative port for security through obscurity?

Explanation:
SSH runs over TCP, not UDP, and typically uses the default port 22. To reduce automated attempts, administrators sometimes configure SSH to listen on a nonstandard port, with 2222 being a common choice. Since SSH requires a reliable, connection-oriented transport, the port must be TCP, making 2222 TCP the correct option for an alternative port. Choosing UDP would break SSH’s reliable delivery, and sticking with 22 TCP would be the standard port rather than an alternative.
