This paper is about the networks and how they work. The origin of networks was the DARPA Net funded by the US Defense Department. From this work the TCP IP framework was developed. Initially this was a private network for the military and universities and then expanded to include for profit activities and became called the Internet. Discuss how the structure of the TCP IP framework has enabled the expansion of the Internet into a worldwide network. Discuss issues with this network. Is it big enough? Are enough IP addresses for all? What is being done under IPV6? Must be typed on 5-7 pages
