IP Address not found in ifconfig/netstat
I'm working on an AIX Unix LPAR (AIX 3.5 00C3C9904C00 as returned by uname -a)
I can access this box using telnet, port 22 using adress IP A and B
A=AA.AA.XX.XX and B=AA.AA.YYY.YYY
I can confirm these 2 are the same space, I can see
I can't find address B listed anywhere... so I wonder what it is related to.
The commands I have tried, after reading your forum, are :
netstat
netstat -in
ifconfig
cat /etc/hosts
In all of this commands I can find address A=AA.AA.XX.XX amongst a list of 4 network interfaces + 127.0.0.1
But i can never find address B=AA.AA.YYY.YYY
Is it the address of a load balancer or other network device that directs the traffic to my box? How can I find out?

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
