Depends on which side of the loadbalancer you're talking about and how it is
configured.

Sounds like he is talking about a source NAT pool. If the box will support
a million simultaneous PATS, it takes 16 addresses to make a PAT pool of
that size. But if you are routing in the data center they can be private, as
only the real servers will see them. If you had a need to do 1 arm across
the Internet a single NAT pool would provide service for a large number of
VIPS. These are featuress of an ACE.
