The port in this case (81) is used to specify the port number in which a local web server is being executed in the “localhost” address. This means that the web server is listening to connection requests at port 81 instead of the predetermined port (80).
In summary, the port is used to identify the specific service or application that is being accessed in an IP address or on a local server.

I’d like to know what’s running on port 81, how can I do that?
To determine what is running on port 81, you can use various methods depending on your operating system. Here are a few options:
1. Command Line Tools:
– On Windows: Open Command Prompt and run the command `netstat -ano | findstr :81`.
– On macOS/Linux: Open Terminal and execute the command `sudo lsof -i :81`.
2. Network Monitoring Tools:
– Use a network monitoring tool like Wireshark or TCPView to analyze network traffic and identify the process using port 81.
3. Online Port Scanners:
– You can use online port scanning services like “canyouseeme.org” or “portchecktool.com” to check the status of port 81 and potentially identify the service running on it.
Remember, if you’re using a personal computer or network, ensure you have the necessary permissions to access and analyze network traffic.
How can I close the operation running on port 81?
To close the operation running on port 81, you can follow these steps:
1. Identify the process using port 81:
– On Windows, open the Command Prompt and run the command: `netstat -ano | findstr :81`
– On macOS or Linux, open the Terminal and run the command: `sudo lsof -i :81`
2. Note down the Process ID (PID) of the process using port 81.
3. Terminate the process:
– On Windows, open the Command Prompt and run the command: `taskkill /PID /F`
– On macOS or Linux, open the Terminal and run the command: `sudo kill `
Replace “ with the actual Process ID you obtained in step 2.
Note: Closing a process forcefully using the `/F` flag may cause data loss or instability. Make sure you are terminating the correct process and consider saving any unsaved work before proceeding.
