INET_TYPE(5) File Formats and Configurations INET_TYPE(5)

NAME


inet_type - default Internet protocol type

SYNOPSIS


/etc/default/inet_type


DESCRIPTION


The inet_type file defines the default IP protocol to use. Currently
this file is only used by the ifconfig(8) and netstat(8) commands.


The inet_type file can contain a number of <variable>=<value> lines.
Currently, the only variable defined is DEFAULT_IP, which can be assigned
a value of IP_VERSION4, IP_VERSION6, or BOTH.


The output displayed by the ifconfig and netstat commands can be
controlled by the value of DEFAULT_IP set in inet_type file. By default,
both commands display the IPv4 and IPv6 information available on the
system. The user can choose to suppress display of IPv6 information by
setting the value of DEFAULT_IP. The following shows the possible values
for DEFAULT_IP and the resulting ifconfig and netstat output that will be
displayed:

IP_VERSION4
Displays only IPv4 related information. The output
displayed is backward compatible with older versions of
the ifconfig(8) and netstat(8) commands.


IP_VERSION6
Displays both IPv4 and IPv6 related information for
ifconfig and netstat.


BOTH
Displays both IPv4 and IPv6 related information for
ifconfig and netstat.


The command-line options to the ifconfig and netstat commands override
the effect of DEFAULT_IP as set in the inet_type file. For example, even
if the value of DEFAULT_IP is IP_VERSION4, the command

example% ifconfig -a6


will display all IPv6 interfaces.

EXAMPLES


Example 1: Suppressing IPv6 Related Output




This is what the inet_type file must contain if you want to suppress IPv6
related output:


DEFAULT_IP=IP_VERSION4
