Online IPv6 Port Scanner,
Web-hosted IPv6 Firewall Tester

IPscan is an online, open source service for testing and analysing IPv6 firewalls. IPscan will report the response to ICMPv6 echo requests, as well as multiple, user-selectable, IPv6 TCP and UDP ports. IPscan offers similar functionality to what you might hope to find in a future IPv6 version of GRC's ShieldsUP® utility. So far over 188,111 IPv6 hosts, and around 13,920,214 IPv6 TCP/UDP ports, have been tested.

About to assess your host's connection to this webserver:

• ✔ No HTTP PROXY detected.
• ✖ The request for this page was made using an IPv4 address (103.233.248.202) and so your machine cannot be tested. Your machine may have accessed this page using IPv4 if your DNS configuration is broken or your browser or DNS service does not correctly prioritise IPv6. If you believe that you do have an IPv6 host with a global unicast address (2000::/3) then further debug assistance can be found in my IPv6 debug suggestions.

Please return when you have a valid IPv6 address to test. If you believe this result to be in error, OR you would like to test a proxy host, then please email me.
