Welcome to IPscan, an open source IPv6 port scanner, or firewall tester, which checks multiple, user-selectable TCP, UDP and ICMPv6 services. IPscan offers much of the functionality you might hope to find in an IPv6 version of GRC's ShieldsUP® utility. So far over 134224 IPv6 hosts, and of the order of 9932550 TCP/UDP ports, have been tested.
About to assess your host'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 proxy host, then please email me.
