20170303:
The entire network stack has been replaced. This requires two updates.
First, BEFORE rebooting, either before or after rebuilding the system,
copy the following new configuration files from /usr/src/etc into /etc:
# cd /usr/src/etc
# cp hosts inetd.conf named.conf nsswitch.conf /etc
Second, AFTER rebooting, set up a new network configuration for your
system. Run netconf(8) and and follow its instructions:
# netconf
If you previously configured your network statically and you forgot its
settings, take a look at /etc/rc.network. That file and /etc/inet.conf
are no longer used now. See the ifconfig.if(5) manual page for more
information about how network settings are specified going forward.
20170223:
Edit your /etc/rc.conf to set rc_configured to YES. If you do not,
your system will refuse to enter multi-user mode after the next reboot.

# Due to rare use of IPv4 compatible address, and security

# file.
#
# For each line from the $ifconfig_xxN variable or the
# /etc/ifconfig.xxN file, we ignore comments and blank lines,
# treat lines beginning with "!" as commands to execute, treat
# "dhcp" as a special case to invoke dhcpcd, and for any other
# line we run "ifconfig xxN", using each line of the file as the
# arguments for a separate "ifconfig" invocation.
#
# In order to configure an interface reasonably, you at the very least
# need to specify "[addr_family] [hostname]" (e.g "inet my.domain.org"),
# and probably a netmask (as in "netmask 0xffffffe0"). You will
# frequently need to specify a media type, as in "media UTP", for
# interface cards with multiple media connections that do not
# autoconfigure. See the ifconfig manual page for details.

# Note that /etc/ifconfig.xxN takes multiple lines. The following

# inet 10.1.1.1 netmask 0xffffff00
# inet 10.1.1.2 netmask 0xffffff00 alias
# inet6 2001:db8::1 prefixlen 64 alias

# starting a line with "!". Refer to ifconfig.if(5) for details.

.Pc .
.Pp
The variable or file will get evaluated only if the interface exists on
the system.
Multiple lines can be placed in a variable or file, and will be
evaluated sequentially.
In the case of a variable, semicolons may be used instead of
newlines, as described in
.Xr rc.conf 5 .
.Ao backslash Ac Ns Ao newline Ac
sequences in files are ignored, so long logical lines may be
made up of several shorter physical lines.
.Pp
Normally, a line will be evaluated as command line arguments to
.Xr ifconfig 8 .
.Dq Li ifconfig Ar nnX
will be prepended on evaluation.
Arguments with embedded shell metacharacters should be quoted in
.Xr sh 1
style.
.Pp
If the line is equal to
.Dq dhcp ,
.Xr dhcpcd 8
will be started for the interface.
However, it is instead recommended that
.Sy dhcpcd
is set to true in
.Xr rc.conf 5
and any per interface configuration or restriction is done in
.Xr dhcpcd.conf 5 .
.Pp
If a line is empty, or starts with
.Sq # ,
the line will be ignored as comment.
.Pp
If a line starts with
.Sq \&! ,
the rest of line will get evaluated as shell script fragment.
Shell variables declared in
.Pa /etc/rc.d/network
are accessible but may not be modified.
The most useful variable is
.Li $int ,
as it will be bound to the interface being configured with the file.
.Pp
For example, the following illustrates static interface configuration:
.Bd -literal -offset indent
# IPv4, with an alias
inet 10.0.1.12 netmask 255.255.255.0 media 100baseTX
inet 10.0.1.13 netmask 255.255.255.255 alias
# let us have IPv6 address on this interface
inet6 2001:db8::1 prefixlen 64 alias
# have subnet router anycast address too
inet6 2001:db8:: prefixlen 64 alias anycast
.Ed
.Pp
The following example sets a network name for a wireless interface
(using quotes to protect special characters in the name),
and starts
.Xr dhcpcd 8 :
.Bd -literal -offset indent
ssid 'my network'
dhcp
.Ed
.Pp
The following example is for dynamically-created pseudo interfaces like
.Xr gif 4 .
Earlier versions of
.Pa /etc/rc.d/network
required an explicit
.Sq create
command for such interfaces,
but creation is now handled automatically.
.Bd -literal -offset indent
up
# configure IPv6 default route toward the interface
!route add -inet6 default ::1
!route change -inet6 default -ifp $int

.Os
.Sh NAME
.Nm route.conf
.Nd static routes config file
.Sh DESCRIPTION
The
.Nm
file is read by the
.Pa staticroute
rc.d script during system start-up and shutdown,
and is intended for adding and removing static routes.
.Ss FILE FORMAT
Lines starting with a hash
.Pq Sq #
are comments and ignored.
Lines starting with a plus sign
.Pq Sq +
are run during start-up,
while lines starting with a minus sign
.Pq Sq \-
are run during system shutdown.
If a line starts with a
.Sq \&! ,
the rest of the line will get evaluated as a shell script fragment.
All other lines are passed to
.Xr route 8 .
During start-up, they are passed behind a
.Dq Ic route add \-
command and during shutdown behind a
.Dq Ic route delete \-
command.
.Sh FILES
.Bl -tag -width XXetcXrouteXconfXX
.It Pa /etc/route.conf
The
.Nm
file resides in
.Pa /etc .
.It Pa /etc/rc.d/staticroute
.Xr rc.d 8
script that parses
.Nm .
.El
.Sh EXAMPLES
In this example, the interface for the desired routing changes is set,
the IP address on that interface is determined, and a route is added
during startup, or deleted during system shutdown.
.Bd -literal -offset indent
# Set interface and determine current IP address for added route.
!ifname=bnx0
!ipaddr=$(/sbin/ifconfig ${ifname} | awk '$1 == "inet" {print $2}')
net 10.10.1 -interface ${ipaddr}
.Ed
.Pp
In this example,
IP forwarding is turned on during
start-up, and a static route added for 192.168.2.0.
During system shutdown, the route is removed
and IP forwarding turned off.
.Bd -literal -offset indent
# Turn on/off IP forwarding.
+sysctl -w net.inet.ip.forwarding=1
-sysctl -w net.inet.ip.forwarding=0
net 192.168.2.0 -netmask 255.255.255.0 192.168.150.2
