About Port Scanner
A port scanner is a network security tool that probes a server or host for open ports. It helps identify which services are running and accessible on a target system.
Open Ports
Ports that are actively listening and accepting connections. These indicate running services.
Closed Ports
Ports that are not listening for connections. The host responded but no service is running on this port.
Filtered Ports
Ports that didn't respond within the timeout period. May be blocked by a firewall or the service is slow to respond.
