# IPscan - Online IPv6 Port Scanner & Firewall Tester

## About
IPscan provides an open-source online tool for testing and analysing IPv6 firewalls and scanning IPv6 ports.

## Overview
IPscan offers a free online facility to test IPv6 firewalls and scan multiple user-selectable IPv6 TCP, UDP, and ICMPv6 services. It offers similar functionalities to what you might expect from a future IPv6 version of ShieldsUP™. Users can select different scanning options based on their test host's configuration and requirements. A separate wiki site provides additional information and privacy details.

## Services
IPscan provides multiple versions of the IPv6 firewall scanner, targeting different user needs. These include a standard offering suitable for most desktop browsers, a faster parallel-testing version, and a lightweight text-only version compatible with non-javascript browsers, such as w3m, lynx or even curl/wget.

## Additional Resources
Detailed background information, privacy policies, and IPv6 debugging suggestions are made available through the IPscan wiki to support users in comprehensively testing and understanding their IPv6 settings.
