[Linux-cluster] help understanding How service ip works

[ESGLinux]

WOW!

2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast qlen
1000
    link/ether 00:0c:29:2a:02:db brd ff:ff:ff:ff:ff:ff
    inet 192.168.1.195/24 brd 192.168.1.255 scope global eth0
    inet 192.168.1.184/24 scope global secondary eth0
    inet6 fe80::20c:29ff:fe2a:2db/64 scope link
       valid_lft forever preferred_lft forever

here is the litle B.....!!!

2 question brings to my mind.

first, why ipconfig dont show it?

second, why hell I thought it was related to multicast???? I thought I have
read about it anywhere...


Thank you ALL for your help (again....)
