The destination port number can be found by using a few different methods.
1. Using a Port Scanner: Port scanners are tools that allow you to scan a system or network for open ports, and identify which ports are associated with which services. This is the most reliable method for finding the destination port number.
2. Looking at Packet Headers: If you have access to packet headers, you can look for the “destination port” field, which will contain the port number.
3. Using the Command Line: You can use the “netstat -a” command to list all the active connections, and look for the port number associated with the destination IP address.
4. Analyzing Network Traffic: If you have access to the network traffic, you can look for the port number in the packets themselves. This may require you to use a packet analyzer or protocol analyzer.
