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.
* rdnssd: Recursive DNS Servers discovery Daemon
This autoconfigures the list of DNS servers through stateless IPv6 autoconfiguration (RFC5006).
