Are you wondering how to find your web server port number? Look no further! In this tutorial, we will guide you through the process of discovering this essential piece of information.

What is a Web Server Port Number?

A web server port number is a communication endpoint that allows servers and clients to exchange data over the internet. It acts as a door for incoming and outgoing network traffic, ensuring that data reaches the correct application or service running on the server.

Why Do You Need to Know Your Web Server Port Number?

Knowing your web server port number is crucial for various reasons. For instance:

  • Running Multiple Services: If you are hosting multiple websites or services on a single server, each might require a unique port number to function correctly.
  • Firewall Configuration: Understanding your port number is essential when configuring firewalls and network security settings. Opening the wrong ports can lead to security vulnerabilities or prevent access to your website.
  • Troubleshooting: In case of any issues with your web server, knowing the port number can help diagnose problems and ensure smooth communication between different components.

Finding Your Web Server Port Number

To find your web server port number, follow these steps:

Step 1: Check Common Default Ports

In many cases, web servers use well-known default ports. Here are some common ones:

  • HTTP: The default port for HTTP is 80.
  • HTTPS: The default port for HTTPS is 443.
  • FTP: The default port for FTP is 21.

If your web server is running on one of these ports, you can access it by navigating to:

Step 2: Check Server Configuration Files

If your web server is not using the default ports, you can find the port number by checking the server configuration files. The location of these files depends on the web server software you are using.

In Apache, for example, the main configuration file is often located at:


In this file, search for the line containing “Listen”. The number next to it specifies your port number.

Step 3: Use Network Port Scanning Tools

If you are unable to locate the port number through the above methods, network port scanning tools can help. These tools scan your server’s listening ports and display their status and associated services.


Finding your web server port number ensures proper communication between clients and servers. By understanding this important piece of information, you can configure firewalls correctly, troubleshoot potential issues, and manage multiple services effectively.

We hope this tutorial has helped you in discovering your web server port number. Happy hosting!
