The rears 1989-96 was another pivotal period for what was effectively known as the Internet, stressing the fact that the original ARPANET had been followed by myriad of fast growing sub-networks operating in the U.S. and internationally.

At the same time the number of hosts as well as the network traffic grew at an enormous rate.
