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. Nmap is a tool for gathering more information about all the nodes on a network. It uses novel techniques to scan a network using IP packets, such as multicasting and invalid header addresses. The release of the software is timed to coincide with this year’s World IPv6 Launch, in which Internet Service Providers and Web companies pledge to offer IPv6 services.”]
