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 for multiple, user-selectable, IPv6 TCP and UDP ports. IPscan now reports responses received 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 202,922 IPv6 hosts, and around 19,886,350 IPv6 TCP/UDP ports, have been tested.
About to assess your machine's connection to this webserver:
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 proxied or deny-listed host, then please email me.
IPscan is a free, open-source network utility engineered to audit IPv6 firewall profiles. It provides an automated external vector to evaluate host security postures, operating similarly to an IPv6-native implementation of Gibson Research Corporation's ShieldsUP!® utility.
Global Telemetry Data: To date, IPscan has audited over 202,922 unique IPv6 hosts across approximately 19,886,350 TCP/UDP ports.
