Outgoing port tester

This server listens on all TCP ports, allowing you to test any outbound TCP port.

You have reached this page on port 25050 (from http host header).

Your network allows you to use this port. (Assuming that your network is not doing advanced traffic filtering.)

Network service: unknown
Your outgoing IP: 3.148.115.187

Test a port using a command

$ telnet portquiz.net 25050 
Trying ...
Connected to portquiz.net.
Escape character is '^]'.

$ nc -v portquiz.net 25050 
Connection to portquiz.net 25050 port [tcp/daytime] succeeded!

$ curl portquiz.net:25050 
Port test successful!
Your IP: 3.148.115.187

$ wget -qO- portquiz.net:25050 
Port test successful!
Your IP: 3.148.115.187

# For Windows PowerShell users
PS C:\> Test-NetConnection -InformationLevel detailed -ComputerName portquiz.net -Port 25050

Test a port using your browser

In your browser address bar: http://portquiz.net:XXXX

Examples:
http://portquiz.net:8080
http://portquiz.net:8
http://portquiz.net:666

Your browser can block network ports normally used for purposes other than Web browsing. In this case you should use the telnet or netcat commands to test the port.

Please also note that this server uses some port for real services (22, 25), so testing with your browser on those ports will not work.

Rate limiting

05/06/2020 : I had to set up Rate limiting on new connections by IP, otherwise the charge was too high for the small portquiz VM. Sorry for that.
