I think it is always better to think "in ip terms" instead of "in
ifconfig terms" with respect to multiple IP addresses assigned to the
same network interface.
I don't know exactly for "ifconfig", but the syntax for "ip address"
states clearly what seems to be happening behind the scenes:
# ip address add 172.16.1.1/24 broad + dev eth1
# ip address add 172.16.2.1/24 broad + dev eth1
# ip address add 172.16.3.1/24 broad + dev eth1
So what you are doing is assigning several IP to the same physical
interface, and you deal just with IP, anything else.
# ip address show dev eth1
2: eth1: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast qlen 1000
link/ether 00:05:1c:09:f2:14 brd ff:ff:ff:ff:ff:ff
inet 192.168.1.12/24 brd 192.168.1.255 scope global eth0
inet 172.16.1.1/24 brd 172.16.1.255 scope global eth0
inet 172.16.2.1/24 brd 172.16.2.255 scope global eth0
inet 172.16.3.1/24 brd 172.16.3.255 scope global eth0
Greetings.
