RandiCMP6 Sends all ICMPv6 type and code combinations to target. It is a part of IPv6 Toolkit. IPv6 toolkit is a set of IPv6 security assessment and trouble-shooting tools. It can be leveraged to perform security assessments of IPv6 networks, assess the resiliency of IPv6 devices by performing real-world attacks against them, and to trouble-shoot IPv6 networking problems. The tools comprising the toolkit range from packet-crafting tools to send arbitrary Neighbor Discovery packets to the most comprehensive IPv6 network scanning tool out there (our scan6 tool).
