IP-Aliasing:
============
IP-aliases are additional IP-addresses/masks hooked up to a base
interface by adding a colon and a string when running ifconfig.
IP-aliases are an obsolete way to manage multiple IP-addresses/masks
per interface. Newer tools such as iproute2 support multiple
address/prefixes per interface, but aliases are still supported
for backwards compatibility.
An alias is formed by adding a colon and a string when running ifconfig.
This string is usually numeric, but this is not a must.
IP-Aliases are avail if CONFIG_INET (`standard' IPv4 networking)
is configured in the kernel.
o Alias creation.
Alias creation is done by 'magic' interface naming: eg. to create a
200.1.1.1 alias for eth0 ...

If the base device is shut down the added aliases will be deleted
too.
