Online IPv6 Port Scanner,
Web-hosted IPv6 Firewall Tester

IPscan is a free 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 197,590 IPv6 hosts, and around 19,363,800 IPv6 TCP/UDP ports, have been tested.

NOTE: a new IPscan release with additional reporting is undergoing testing. If the results do not match your expectations then please contact me using the email link provided in the test results page.

If you have verified that the address above is YOUR IPv6 address, then please click on one of the following links to test your machine:

  1. Original IPv6 firewall scanner (requires Javascript, but gives ongoing updates as the test progresses)
  2. FASTER version of the above (requires Javascript, NOTE: some OS/firewalls drop high-rate ICMPv6 responses)
  3. Lightweight IPv6 firewall scanner (compatible with text browsers, e.g. Lynx/w3m, but takes up to 90s to return a result)
  4. FASTER version of the above (text browsers, NOTE: some OS/firewalls drop high-rate ICMPv6 responses)
