Chapter 15 - IP: Software To Create A Virtual Network

1. Introduction
2. Protocol: An Agreement For Communication
3. Basic Functionality: The Internet Protocol
4. IP Software On Every Machine
   Because all Internet services use the Internet Protocol, a computer must have IP software before it can use the Internet.
5. Internet Packets Are Called Datagrams
   Each packet sent across the Internet must follow the format specified by the Internet Protocol. Such packets are called IP datagrams.
6. The Illusion Of A Giant Network
   The Internet operates like a single network that connects several million computers. IP software allows any computer to send an IP datagram to any other computer
7. The Reality Of Internal Structure
8. Datagrams Travel In Packets
9. Every Computer Is Assigned A Unique Address
10. Internet Addresses (IP addressses)
11. An Odd IP Address Syntax
12. IP Addresses Are Not Random
13. An Example Trip Through The Internet (use tracert from the command line: ex. tracert jaring.nmhu.edu)
14. IPv4 (current protocol) vs. IPv6 (new protocol which allows more addresses and includes additional security features)
