Port Checker
Check if a port is open on your IP or any host
What Is Port Checking?
A port check tests whether a specific network port on a host is accepting connections. This is useful for verifying that port forwarding is configured correctly, firewalls aren't blocking traffic, and services are running as expected.
Common Uses
- Verifying port forwarding rules on your router
- Checking if a firewall is blocking a specific port
- Confirming that a web server, SSH, or game server is reachable
- Diagnosing connectivity issues with remote services
