Yes and no. We see a lot of NATting being done purely to masquerade
internal networks, but it is also very valuable as a security measure;
consider the next-to-impossibility of hitting an individual machine
behind a NATting firewall. Also, consider the case of a
load-balancing switch; typically these have a "real" IP on the front
end, and they forward packets via NAT to multiple servers on private
addresses. This is much harder to do using "real" IP addresses across
NAT has its uses even in a larger address space.
