What is the default port of IP-Winbox?

The default port for IP-Winbox is TCP 8291. This port is specifically designated for the Winbox application, which is a graphical user interface used to manage MikroTik routers. When a network administrator uses Winbox to connect to a MikroTik device, the software communicates over this TCP port, establishing a secure connection to perform various router management tasks.

Using TCP 8291 allows for efficient communication as it is optimized for the features and functions offered by Winbox, such as easy navigation through the router's interface, managing configurations, and monitoring performance. This default port plays a critical role in ensuring that all data packets sent and received during a Winbox session are correctly routed to the MikroTik device.

The other options specified do not align with the standard configuration for IP-Winbox, thereby making them incorrect.
