Description: IPv6 diagnostic tools
ndisc6 gathers a few diagnostic tools for IPv6 networks including:
  - ndisc6, which performs ICMPv6 Neighbor Discovery in userland,
  - rdisc6, which performs ICMPv6 Router Discovery in userland,
  - rltraceroute6, a UDP/ICMP IPv6 implementation of traceroute,
  - tcptraceroute6, a TCP/IPv6-based traceroute implementation,
  - tcpspray6, a TCP/IP Discard/Echo bandwidth meter,
  - addrinfo, easy script interface for hostname and address resolution,
  - dnssort, DNS sorting script.

On various BSDs and Solaris platforms and other such unices you will
find separate ndsol (client) and ndsold (daemon) too btw.

Greets,
Jeroen
