Welcome to IPscan, the 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 105158 IPv6 hosts, and of the order of 7781650 IPv6 ports, have been tested. The TCP Port Scan will test an IP Address for common open ports. This technique of testing for listening services is known as a port scan . Try our advanced online port scanner that is able to scan any IP Address or IP range and all 65535 ports. Assuming that it's a TCP (rather than UDP) port that you're trying to use: On the server itself, use netstat -an to check to see which ports are listening.. From outside, just use telnet host port (or telnet host:port on Unix systems) to see if the connection is refused, accepted, or timeouts.

The open port scanner features in Engineer's Toolset are built to offer comprehensive functions to help you scan for devices and secure, troubleshoot, and document your network. Using a port scanner to check for open ports is important but running the tool alone may not be enough to secure your network.

A port scanner is a software application or online tool designed to probe a network host for open ports. This is often used by administrators to verify security policies of their networks and by attackers to identify running services on a host with the view to compromise it.
