traceroute6

Syntax:

traceroute6 [-dIlnrv] [-f firsthop] [-g gateway]
            [-m hoplimit] [-p port] [-q probes] [-s src]
            [-w waittime] target [datalen]

-d: Enable debugging.
-f firsthop: Specify how many hops to skip in the trace.
-g gateway: Specify the intermediate gateway (traceroute6 uses the routing header).
-I: Use ICMP ECHO instead of UDP datagrams.
-l: ("el") Print both the host hostnames and numeric addresses (normally, only hostnames are printed; or, if -n is specified, only numeric addresses).
-m hoplimit: Specify the maximum hoplimit.
-n: Don't resolve the numeric address to a hostname.
-p port: Set the UDP port number to port.
-q probes: Set the number of probes per hop count to probes.
-r: Bypass the normal routing tables and send directly to a host on an attached network. If the host isn't on a directly attached network, an error is returned. You can use this option to "ping" a local host through an interface that has no route through it (for example, after the interface was dropped by routed).
-s src: Use this source IPv6 address.
-v: Be verbose.
-w waittime: Specify the delay time between probes.
target: The destination hostname or IP number.
datalen: Increase the packet size by this amount. By default, the size is zero and no data is sent.

This utility prints the route that the IPv6 packets take to the destination. For more information, see traceroute .
