Nmap (“Network Mapper”) is a free and open source utility for network exploration or security auditing. Many systems and network administrators also find it useful for tasks such as network inventory, managing service upgrade schedules, and monitoring host or service uptime. Nmap uses raw IP packets in novel ways to determine what hosts are available on the network, what services (application name and version) those hosts are offering, what operating systems (and OS versions) they are running, what type of packet filters/firewalls are in use, and dozens of other characteristics. It was designed to rapidly scan large networks, but works fine against single hosts. Nmap runs on all major computer operating systems, and official binary packages are available for Linux, Windows, and Mac OS X. In addition to the classic command-line Nmap executable, the Nmap suite includes an advanced GUI and results viewer (Zenmap), a flexible data transfer, redirection, and debugging tool (Ncat), and a utility for comparing scan results (Ndiff).
Though Nmap has been supporting IPv6 since 2002, there were a few limitations with raw packet scans (SYN scan, UDP scan, ICMP ping packets,etc.) not being supported. This limitation has finally been emilinated!
However, the following features related to IPv6 scanning are still not completely supported:-
OS detection.
Protocol scan.
IPv6 CIDR address notation.
Neighbor Discovery-based host discovery (analog to ARP scan).
Multicast host discovery.
Windows Teredo tunnels (a system for tunneling IPv6 to systems which don’t support it natively) are not supported by the raw system, but you can still use -6 with –unprivileged to scan through those interfaces.
When scanning link local IPv6 addresses (they start with fe80), you might need to put the interface name at the end like you sometimes do with ping6 and other system IPv6 tools (e.g. fe80::9afc:22ee:bc91:3e1d%eth0)
Whats more is that the same support has been added to the Nmap scanme engine too.
