IPscan: Online IPv6 Firewall Tester & Port Scanner

Web-hosted IPv6 Firewall Security & Network Diagnostics

IPscan is a free, online, open-source service for testing IPv6 firewall responses to ICMPv6 pings and connection attempts to multiple, user-selectable, TCP and UDP ports. IPscan also identifies responses from intermediary (aka mid-point or transit) network devices. IPscan offers functionality similar to what you might expect from a future IPv6 version of GRC's ShieldsUP® utility. So far over 210,716 IPv6 hosts, and around 20,650,150 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)
