NDisc6 is a small collection of useful tools for IPv6 networking. It includes
the following programs:

ndisc6: ICMPv6 Neighbor Discovery tool
Performs IPv6 neighbor discovery in userland. Replaces arping from the IPv4
world. Can easily be used to monitor other hosts through scripts.

rdisc6: ICMPv6 Router Discovery tool
Queries IPv6 routers on the network for advertised prefixes. Can be used to
detect rogue IPv6 routers, monitor legitimate IPv6 routers. Can also be
used to force the local host into doing IPv6 autoconfiguration.

tcptraceroute6: lightweight IPv6 tcptraceroute
Use TCP/IPv6 packets to perform a traceroute. Very similar from the user’s
perspective to the famous Michael Toren’s tcptraceroute from the IPv4
world.

traceroute6: IPv6 traceroute
Yet another UDP/IPv6 traceroute. Most of the code is shared with
tcptraceroute6 above.
