🔌 TCP Port Check · Common Services
Port Scanner
Check if common ports are open or closed on any domain or IP address. Identify running services for network diagnostics and security audits.
Select a preset or the tool will scan all common ports.
Enter a domain or IP and click Scan Ports.
⚠Only scan servers you own or have explicit permission to test. This tool checks port reachability via HTTP fetch probes — results indicate service availability, not full TCP state.
