traceroute6print the route IPv6 packets take to network host

traceroute6 [-AcDdIlnrSv] [-f firsthop] [-g gateway] [-m hoplimit] [-p port] [-q probes] [-s src] [-V rtable] [-w waittime] host [datalen]

The traceroute6 utility details the route IPv6 packets take to reach a network host.

The options are as follows:

Look up the AS number for each hop address. Uses the DNS service described at
Do not increment the destination port number in successive UDP packets. Rather, all UDP packets will have the same destination port, as set via the -p flag (or 33434 if none is specified).
Dump the packet data to standard error before transmitting it.
Debug mode.
Specify how many hops to skip.
Specify an intermediate gateway (traceroute6 uses a routing header).
Use ICMP6 ECHO instead of UDP datagrams.
Print both host hostnames and numeric addresses. Normally traceroute6 prints only hostnames if -n is not specified, and only numeric addresses if -n is specified.
Specify a maximum hoplimit.
Do not resolve numeric addresses.
Set UDP port number to port.
Set the number of probes per hop count to probes.
Bypass the normal routing tables and send directly to a host on an attached network. If the host is not on a directly attached network, an error is returned. This option corresponds to the SO_DONTROUTE socket option; it can be used to ping a local host through an interface that has no route through it (e.g. after the interface was dropped by a routing daemon).
Print how many probes were not answered for each hop.
Specify the source IPv6 address to be used.
Be verbose.
Set the routing table to be used.
Specify the time delay between probes.

The traceroute6 utility exits 0 on success, and >0 if an error occurs.

The traceroute6 command first appeared in the WIDE Hydrangea IPv6 protocol stack kit.
