What is 4443 port used for?
Side note: UDP port 4443 uses the Datagram Protocol, a communications protocol for the Internet network layer, transport layer, and session layer. This protocol when used over PORT 4443 makes possible the transmission of a datagram message from one computer to an application running in another computer.
What is the use of port 17?
PORT 17 – Information Used to receive remote QOTDs. Used for social engineering attacks, where users receive fake instructions to verify passwords , etc.
Is port 4443 Secure?
UDP port 4443 would not have guaranteed communication in the same way as TCP. Because protocol TCP port 4443 was flagged as a virus (colored red) does not mean that a virus is using port 4443, but that a Trojan or Virus has used this port in the past to communicate.
How do I know if my connection is TCP or UDP?
Proceed as follows.
- In the settings of the TCP/UDP connection you set the IP of the partner to the IP address of the PC.
- Enter number 7 or 9 as the partner port (see below for difference).
- Load the configuration.
- Test the connection and check the connection status. You can also send data.

What is the Transmission Control Protocol (TCP) port 6?
TCP port 6 uses the Transmission Control Protocol. TCP is one of the main protocols in TCP/IP networks. TCP is a connection-oriented protocol, it requires handshaking to set up end-to-end communications. Only when a connection is set up user’s data can be sent bi-directionally over the connection. Attention!
What are TCP and UDP port numbers?
Unsourced or poorly sourced material may be challenged or removed. This is a list of TCP and UDP port numbers used by protocols for operation of network applications. The Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP) only need one port for duplex, bidirectional traffic.
