man ifconfig

alias Establish an additional network address for this interface. This
is sometimes useful when changing network numbers, and one wishes
to accept packets addressed to the old interface. If the address
is on the same subnet as the first network address for this
interface, a non-conflicting netmask must be given. Usually
0xffffffff is most appropriate.

-alias Remove the network address specified. This would be used if you
incorrectly specified an alias, or it was no longer needed. If
you have incorrectly set an NS address having the side effect of
specifying the host portion, removing all NS addresses will allow
you to respecify the host portion.



ifconfig device_node alias xxx.xxx.xxx.xxx netmask xxx.xxx.xxx.xxxx


example :

ifconfig vr0 alias 192.168.254.90 netmask 255.255.255.255
