The Internet started in Sept. 1981 when a new set of protocols - rules for who talks when and how - began being used, called "TCP/IP". They were used on a network that had already been running since 1969, using an older protocol called "NCP". Current network addresses look like " 128.9.176.20", which is ISI's webserver ( www.isi.edu). The first network addresses all started with "10.", i.e., " 10.0.0.1", and described everyone on the first ARPAnet (the precursor to the Internet). Those addresses aren't in use any more; they're reserved for 'tests' (RFC1918 describes this) Read more about it here http://www.postel.org/internet-history/ Visit also http://nxoc01.cern.ch/hypertext/WWW/TheProject.html/ but you can find more helpful informations via http://www.w3.org/History.html/ Hope you Enjoy the class.
