TCP Open Port Scanner

TCP Open Port Scanner is a fast and simple tool for checking if specific TCP ports are open across any IP range.

Unlike the Network Service Scanner, which sends actual protocol requests to validate services, this tool only checks if the port is open and accepting connections.

It's ideal when you want a quick status check or when full service validation isn't needed. The scanner includes several predefined port sets:

• Well Known Ports (56 entries)
• Trojans (87 commonly used backdoor ports)
• Extended Well Known Ports (3400+)
• Custom Range

Whether you're scanning a single host or an entire subnet, the tool quickly shows open ports with inferred service names when possible.

A built-in summary groups open ports by service and shows total scan time and port count.

It's beneficial for security audits, firewall testing, or quick service mapping and perfectly complements the Network Service Scanner when you need both availability and verification.
