What he refers to is sometimes known as NAT - Network Address Translation.
Ip-masquerading is commonly used, partly due to this being the term Linux
uses for its implementation.
Basically, you have a host (or router or whatnot) take alla packets from a
host or network, change the source ip-number, ports etc. and pass them on
to someone else. Whith incoming packages the procedure is revered. Hence a
number of hosts can get by with only a single ip-address.
