New Nmap probes IPv6 networks

Nmap version 6.0 features many significant enhancements, including full support for IPv6

Preparing for the eventual widespread conversion to IPv6, the Nmap Project has updated its namesake security scanning tool so it can scan IPv6 networks using a variety of novel techniques.

Nmap Security Scanner version 6.0 is the first major update for the free, open source security-testing tool since version 5 was released in 2009, and features some major updated and new features, as well as a variety of cosmetic changes and performance improvements. Overall, the project and associated volunteers have made more than 3,900 changes to the code base.

The project has timed the release of Nmap 6.0 to coincide with this year's World IPv6 Launch, in which a variety of Internet Service Providers and Web companies -- such as Comcast, AT&T, Facebook and Google -- pledge to offer IPv6 services. Organized by the Internet Society, World IPv6 Launch day will be held June 6 this year.
In addition to IPv6 support, the updated software comes with improvements to the scripting engine and the GUI (graphical user interface). It can also scan a network more quickly and deliver more information about Web hosts. It also comes with a new tool to generate packets and analyze results.

Nmap, short for Network Mapper, is a tool for gathering more information about all the nodes on a network. Although primarily designed for security testing, Nmap is also used by system administrators to inventory the resources on their networks. Using IP packets, it identifies what operating system a host uses, if there are firewalls in place, what ports are open, and a great deal of other related information.
Earlier versions of Nmap offered some IPv6 tools, namely port scans, basic host discovery, version detection, and use of the scripting engine. This release expands upon these capabilities offering a traceroute utility, a neighbor-discovery ping utility and the ability to detect operating systems.
Nmap also expands upon the number of ways that it can scan a IPv6 network. Because even a smaller network's IPv6 address space is too large to scan on a possible address-by-address basis, this software uses a number of novel techniques to find hosts, by clever use of multicasting, invalid header addresses, and other techniques.
