.Sh DESCRIPTION
.Bl -tag -width Ds
.It Fl d
Debug mode.
.It Fl f Ar firsthop
Specify how many hops to skip in trace.
.It Fl g Ar gateway
Specify intermediate gateway
.Po
.Nm
uses routing header
.Pc .
.It Fl I
Use ICMP6 ECHO instead of UDP datagrams.
.It Fl l
Print both host hostnames and numeric addresses.
Normally
.Nm
prints only hostnames if
.Fl n
is not specified, and only numeric addresses if
.Fl n
is specified.
.It Fl m Ar hoplimit
Specify maximum hoplimit.
.It Fl n
Do not resolve numeric address to hostname.
.It Fl p Ar port
Set UDP port number to
.Ar port .
.It Fl q Ar probes
Set the number of probe per hop count to
.Ar probes .
.It Fl r
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
.Xr route6d 8 ) .
.It Fl s Ar src
.Ar Src
specifies the source IPv6 address to be used.
.It Fl v
Be verbose.
.It Fl w Ar waittime
Specify the delay time between probes.
