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  out-
                put  displayed  is backward compatible with older
                versions of the ifconfig(1M) and netstat(1M) com-
                mands.

          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  com-
     mands  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
