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
