inet_type

inet_type(4)							   File Formats 						      inet_type(4)

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(1M) and netstat(1M) 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(1M)
		      and netstat(1M) 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
