traceroute6print the route IPv6 packets will take to the destination


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


Turn on AS# lookups and use the given server instead of the default.
Turn on AS# lookups for each hop encountered.
Debug mode.
-f firsthop
Specify how many hops to skip in trace.
-g gateway
Specify intermediate gateway (traceroute6 uses 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.
-m hoplimit
Specify maximum hoplimit.
Do not resolve numeric address to hostname.
-p port
Set UDP port number to port.
-q probes
Set the number of probe 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 can be used to send probes to a local host through an interface that has no route through it (e.g., after the interface was dropped by route6d(8)).
-s src
Src specifies the source IPv6 address to be used.
Be verbose.
-w waittime
Specify the delay time between probes.


The traceroute6 command exits 0 on success, and >0 on errors.


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