  • VPN and IP Testing Tools
  • Port scan

Port scan

With this simple tool you can check whether any given port is open or closed on your IP. Only TCP protocol can be tested because of the state-less design of UDP. Valid TCP ports are between 1 - 65535

Your IP is: 216.73.216.240

Test your port:

Port is open

Port is open

This port on your IP is open. If you have any service (such as BitTorrent, SSH, web server) listening on this port, traffic will be forwarded and service accessible over this IP:port.

Port is closed

Port is closed

This port on your IP is closed. If any service is listening on this IP (e.g. BitTorrent, SSH, web server), traffic will not be forwarded and service will be inaccessible over this IP:port.
