Add additional IP address to physical card on Debian 7?

Question

Debian

1) Ifconfig eth0:1 10.10.10.10 - Wirth map is created, but after reboot it is naturally demolished.
2) When added to the interface, just
iface eth0:1 inet static
address 10.10.10.10
netmask 255.0.0.0
it does not get up either
3) When added to rc.local /sbin/ifconfig eth0:1 10.10.10.10 - it does not get up either.

This is not a virtual card, but an additional IP. You only see it as just another interface because of the limitations of the OBSOLETE ifconfig utility.
Here is an example:

# Это вывод команды ip a
# Как видите сетевому интерфейсу просто назначили дополнительный IP
[email protected]:~$ ip a
...

3: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
    link/ether f6:8e:be:42:fe:45 brd ff:ff:ff:ff:ff:ff
    inet 192.168.20.117/22 brd 192.168.23.255 scope global eth1
    inet 10.10.10.10/8 brd 10.255.255.255 scope global eth1:1
    inet6 fe80::f48e:beff:fe42:fe45/64 scope link
       valid_lft forever preferred_lft forever

# А это вывод команды ifconfig
# Она не знает ничего о дополнительных IP, так как была написана в те 
# времена, когда о дополнительных IP речи не шло, поэтому
# дополнительный IP она показывает как ещё один сетевой интерфейс 
[email protected]:~$ ifconfig

eth1      Link encap:Ethernet  HWaddr f6:8e:be:42:fe:45
          inet addr:192.168.20.117  Bcast:192.168.23.255  Mask:255.255.252.0
          inet6 addr: fe80::f48e:beff:fe42:fe45/64 Scope:Link

          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          Interrupt:27

This is how it should work:

auto eth0:0
iface eth0:0 inet static
    address 23.99.99.100
    netmask 255.255.255.0

Answer 2

Add to the main interface
And I don't think the mask 255.0.0.0 is correct ;)
