🔍 Port Scanner

What is Port Scanning?

Port scanning is a technique used to identify open ports and services available on a network host. Each port number corresponds to a specific service or protocol – for example, port 80 is typically used for HTTP web traffic, while port 22 is used for SSH connections.

Why Scan Your Ports?

Checking your own open ports is useful for:

• Security Assessment – Identify potentially vulnerable services exposed to the internet
• Firewall Testing – Verify your firewall is properly blocking unwanted connections
• Server Configuration – Confirm your services are accessible as intended
• Troubleshooting – Diagnose connectivity issues with specific applications

Understanding Results

Open: The port is accepting connections. A service is listening and accessible from the internet.

Closed: The port is not accepting connections. Either no service is running, or a firewall is blocking access.

Note: This scanner checks ports from our server to your public IP. Results may differ from local scans due to NAT, firewalls, or ISP restrictions.
