Which port does Microsoft SQL Server listen on by default?

Explanation:
The default port for Microsoft SQL Server is 1433. This is the standard TCP port that the default instance listens on, meaning clients connect to 1433 unless a different port is explicitly configured. The other numbers correspond to other services—21 is FTP, 3389 is Remote Desktop Protocol, and 3306 is MySQL—so they aren’t used by SQL Server by default. If you’re using a named instance, SQL Server can listen on a dynamic or a separately configured port, and the SQL Server Browser helps clients find that port. But for a typical default instance, 1433 is the expected listening port.
