Description: This project shows you how to capture packets on a network, select a specific packet, and examine the IPv4 header data for the packet. You may capture your own data to analyze, or you may start Wireshark, open the ch03_IPv4Fields.pcapng file available from the Student Companion Web site, and skip to Step 8. Start […]

Create a game similar to Hangman  in which a player guesses letters to try to replicate a hidden word.  Be sure to use the following criteria. Store at least eight words in an array [each word should be 5 or more characters] Randomly select one to be the hidden word. Initially, display the hidden word […]

As we saw in the previous topic, IPv6 datagrams use a structure that includes a regular header and optionally, one or more extension headers. This regular header is like the header of IPv4 datagrams, though it has a different format, as we will see shortly. The standards don’t give this header a name; it is […]

“If it ain’t broke, don’t fix it.” I consider this one of my favorite pieces of folk wisdom. I generally like to stick with what works, as do most people. And IP version 4 works pretty darned well. It’s been around for decades now and has survived the growth of the Internet from a small […]

Data transmitted over an internet using IP is carried in messages called IP datagrams. Like all network protocol messages, IP uses a specific format for its datagrams. We are of course looking here at IP version 4 and so we will examine the IPv4 datagram format, which was defined in RFC 791 along with the […]
