IP-Masquerading is what Cisco calls PAT (Port Address Translation).
All connections will appear on the outside to be coming from the same
address, but with different ports.
NAT instead (at least as Cisco means it AFAIK) means allocating a pool
of IP address, and then dynamically binding an address in the
pool to an internal IP address. So connections outside will
appear to arrive from different IP addresses, but with the calling
port being the same as on the originating host.

Others might mean NAT as any kind of manipulation on IP addresses,
ports or protocols done at an intermediate router level.
