You can use this app to check your IP configuration and detect open ports on your connection.
Just type a port in the unique field of the main page or choose one of the common ports and tap the "Check" button.
Also set which part of network you would like to check:
▶ This device (Localhost), or
▶ External IP (ex. Router's IP)
