Which port is commonly used by HTTPS?

Explanation:
HTTPS runs HTTP over TLS/SSL and uses TCP because a reliable connection is needed for the encryption handshake and data transfer. The standard, widely used port for this secure web traffic is 443, which is the default assignment for HTTPS. This makes client and server configurations predictable and interoperable. Port 80 is the unencrypted HTTP counterpart, so it’s not used for secure traffic. UDP port 53 is for DNS, not web content, and TCP port 22 is used for SSH. While HTTPS can be configured to run on non-standard ports, 443 is the common and expected choice for secure web communication.
