IPscan - the online IPv6 Port Scanner,
aka Web-hosted IPv6 Firewall Tester

IPscan is a free, online, open-source service for testing IPv6 firewall responses to ICMPv6 pings and connection attempts targeted at multiple, user-selectable, IPv6 TCP and UDP ports. IPscan now reports responses from intermediary network devices too. IPscan offers functionality similar to what you might expect from a future IPv6 version of GRC's ShieldsUP® utility. So far over 199,525 IPv6 hosts, and around 19,553,450 IPv6 TCP/UDP ports, have been tested.

  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)
