Free Online Opensource IPv6 TCP/UDP Port Scanner

This free-access IPv6 portscan service supports testing of multiple TCP/UDP ports on any internet-connected host with an IPv6 global unicast address (2000::/3), irrespective of your IPv6 provider or device operating system.

Please read, and accept, these important terms and conditions of usage before performing firewall tests using this site:

• This utility is provided by "L'Altro Mondo" as a convenience, and has been developed by Tim Chappell - Do NOT rely on this tool. If you want to be certain that your IPv6 firewall is operating correctly then please use a professional penetration testing (pentest) tool.
• The utility is only intended to test IPv6 hosts. The tester will attempt to connect to a set of predefined UDP ports, as well as one or more TCP ports that you define, targeting the IPv6 address that my webserver determines your web page request originated from.
• Please verify that the IPv6 address reported below is that of your machine, and that you are authorised to perform such a test, prior to beginning the test.
• IMPORTANT: Please do NOT attempt to test machines that are hidden behind HTTP proxies, unless you also administer the proxy and intend that machine to be tested.

For further background information and a screenshot of the typical results page please visit the Tim's IPv6 Port Scan wiki. Thanks Tim :)

Full source-code available via github.

If you don't currently have an IPv6 connected host, but are interested in getting one, then try one of the various IPv6 Tunnel brokers, like Hurricane Electric or SixXS.net.
