The interface's connected list keeps all addresses assigned to the
that interface. For instance, if you have 2 ethernet cards configured
as follows:
$ /sbin/ifconfig | egrep 'eth0|inet'
eth0 Link encap:Ethernet HWaddr 00:10:5A:AB:F9:4D
inet addr:1.1.1.1 Bcast:1.1.1.255 Mask:255.255.255.0
eth0:0 Link encap:Ethernet HWaddr 00:10:5A:AB:F9:4D
inet addr:2.2.2.2 Bcast:2.2.2.255 Mask:255.255.255.0
eth1 Link encap:Ethernet HWaddr 00:10:5A:F0:01:B2
inet addr:3.3.3.3 Bcast:3.3.3.255 Mask:255.255.255.0
Then the connected lists are:
eth0: connected list = 1.1.1.1/24, 2.2.2.2/24
eth1: connected list = 3.3.3.3/24
