Sure you can do that.  Remember the rule though, that the first IP from
each different network configured on an interface must use the natural
netmask for that network.  Second and subsequent addresses from each
different network can either use the all-ones (/32) netmask, or the
natural netmask.  This only changed a few years ago, so there's still a
lot of advice going around saying you should use the older all-ones
style, but in actuality you can do it which ever of those ways you want
and it won't make any functional difference.

	Cheers,
