71.Sh DESCRIPTION
72.Bl -tag -width Ds
73.It Fl d
74Debug mode.
75.It Fl f Ar firsthop
76Specify how many hops to skip in trace.
77.It Fl g Ar gateway
78Specify intermediate gateway
79.Nm (
80uses routing header).
81.It Fl m Ar hoplimit
82Specify maximum hoplimit.
83.It Fl l
84Print both host hostnames and numeric addresses.
85Normally
86.Nm

91is specified.
92.It Fl n
93Do not resolve numeric address to hostname.
94.It Fl p Ar port
95Set UDP port number to
96.Ar port .
97.It Fl q Ar probes
98Set the number of probe per hop count to
99.Ar probes .
100.It Fl r
101.It Fl s Ar src
102.Ar Src
103specifies the source IPv6 address to be used.
104.It Fl v
105Be verbose.
106.It Fl w Ar waittime
107Specify the delay time between probes.
