38 DESCRIPTION
39 The netstat command displays the contents of certain network-related
40 data structures in various formats, depending on the options you
41 select.
42
43 The netstat command has the several forms shown in the SYNOPSIS
44 section, above, listed as follows:
45
46 o The first form of the command (with no required arguments)
47 displays a list of active sockets for each protocol.
48
49 o The second, third, and fourth forms (-g, -p, and -s options)
50 display information from various network data structures.
51
52 o The fifth form (-m option) displays STREAMS memory
62
63 o The ninth form (-D option) displays the state of DHCP on one
64 or all interfaces.
65
66 These forms are described in greater detail below.
67
68 With no arguments (the first form), netstat displays connected sockets
69 for PF_INET, PF_INET6, and PF_UNIX, unless modified otherwise by the -f
70 option.
71
72 OPTIONS
73 -a
74
75 Show the state of all sockets, all routing table entries, or all
76 interfaces, both physical and logical. Normally, listener sockets
77 used by server processes are not shown. Under most conditions, only
78 interface, host, network, and default routes are shown and only the
79 status of physical interfaces is shown.
80
81
82 -f address_family
83
84 Limit all displays to those of the specified address_family. The
85 value of address_family can be one of the following:
86
87 inet
88 For the AF_INET address family showing IPv4 information.
89
90
91 inet6
92 For the AF_INET6 address family showing IPv6 information.
93
94
95 unix
96 For the AF_UNIX address family.

80
81
82 -c
83
84 Print IPv4 networks using CIDR (x.y.z.a/NN) notation with the -i,
85 -r, and -M options. IPv6 networks default to this, but due to
86 backward compatibility, IPv4 ones do not without this flag. A
87 noncontiguous IPv4 netmask will print "/NM" if this flag is
88 enabled.

91 -f address_family
92
93 Limit all displays to those of the specified address_family. The
94 value of address_family can be one of the following:
95

97 For the AF_INET address family showing IPv4 information.
98
99
100 inet6
101 For the AF_INET6 address family showing IPv6 information.
