.Sh DESCRIPTION
The
.Nm
command is a stable replacement for the
.Xr ifconfig 8
and
.Xr ndd 8
commands.
It is used to create IP interfaces and to configure IP addresses on those
interfaces.
It is also used to get, set or reset properties on interfaces, addresses and
protocols.
.Pp
For subcommands that take an
.Em addrobj ,
the
.Em addrobj
specifies a unique address on the system, and must be unique itself.
It is made up of two parts, delimited by a
.Sq / .
The first part is the name of the interface and the second part is an arbitrary
string up to 32 alphanumeric characters long, where the first character must be
alphabetic
.Pq e.g. a-z,A-Z .
For example,
.Qq lo0/v4
is a loopback interface
.Em addrobj
name, which could also be called
.Qq lo0/ipv4loopback .
Consumers should note that this length limit may be lifted in the future.
.Pp
For subcommands that take a
.Em protocol ,
this can be one of the following values:
.Cm ip ,
.Cm ipv4 ,
.Cm ipv6 ,
.Cm icmp ,
.Cm tcp ,
.Cm sctp
or
.Cm udp .
.Sh SUBCOMMANDS
When invoked with no arguments,
.Nm
shows the current address properties, in the same way as
.Nm
.Cm show-addr .
.Pp
The following subcommands are supported:
.Pp
.Bl -tag -compact -width Ds
