...The History of IPv4 And Beginning of IPv6 Mathew J. Jones ITT Technical Institute IPv6 is the future of Internet Protocol, but first, it is important to recognize and identify IPv4 and talk a little about its history. The history of IPv6 is also something that needs to be discussed as even though it has not been implemented yet, it does have a brief history. Also, we can compare and contrast the two Internet Protocols with the advantages and disadvantages of both. There will also be mention of DHCP, and how DHCP servers can be configured to use IPv6. First, it is important to talk about the history of IPv4, but first IP’s, or Internet Protocol, main principle is routing network packets. This essentially creates internetworking, which establishes the Internet. In IP, or at the IP level, the main task is to deliver packets from the host to the destination host. But to do this the host and the destination host needs an address, and this is where IPv4 (and later IPv6) comes into play. IPv4 was then created to hand this, “In the 1980s, when the Internet went live to the public, IPv4 was the fourth revision of Internet Protocol, and the first offered to the public. IPv4 is the general standard of delivery of information between devices connected to the Internet.” (Dooly, 2013) After this, the Department of Defense eventually took on IPv4 as it’s own preferred method. It became the universal method of addressing of the world. IPv4 uses a 32-bit address of numbers and...

...Router Passwords Step 4. Configure the router to require a password of ciscopress when connecting through the console. To do so, start by issuing the line con 0 configuration command, which moves you to console line configuration mode. What does the command prompt look like after using this command? The command line now says: Router(config-line)# Step 11. Press Enter. Does the router prompt you for a password? Does the password ciscopress work? Yes and yes Step 12. Use the enable command to move from user mode to enable mode. Which of the two passwords (fred or barney) works? Which configuration command did you use to con- figure that password? Barney was the password that worked, and enable secret barney Lab 10: Configuring Router IP Settings Step 4. Use the show ip interface brief command to view all interfaces. Which interfaces have an IP address configured? What are the addresses and the corresponding masks? None of the interfaces have an IP address configured Step 10. Use the show ip interface brief command to view all interfaces. Is the router’s Fa0/0 IP address now listed? What is the IP address? Yes the IP address is now listed. The IP address is 10.1.1.4 Step 11. Confirm that R1’s Fa0/0 interface is working by pinging PC1 (10.1.1.1). Did the command output imply that R1 can send packets to and from PC1? Yes it implies that R1 can send packets Lab 22: Terminal History Step 5. Press Up Arrow again to bring up your show ip route connected command...

...Analyses of Industry International Paper Company (IP) is one of the world’s largest manufacturers of paper and paper products. Their products include a wide variety of paper products, consumer packaging materials, industrial packaging materials, and pulp products. In addition, IP collects and recycles recovered paper. History IP began in 1898 as a merger of 17 pulp and paper mills from Massachusetts to New York. IP led the newsprint industry until 1913, when trade regulations revised to promote Canadian imports and later, in 1921, labor conflicts within IP contributed to a decline in IP’s market share. However, IP rallied by creating a Canadian subsidiary, expanding into the South by acquiring and building new mills, consolidating its northern operations, and diversifying its product line from primarily newsprint, to book and bond products, and later, corrugated containers. This diversification aided IP in surviving the Great Depression, and continued through the 1930’s. IP continued to reap profits and expand the company through the 50’s and 60’s, into North American and overseas, eventually expanding into places such as French West Indies, Mexico, and France. The 1970’s found IP divesting itself of several plants and mills, and in 1976, J. Stanford Smith, facilitated a major company reorganization revised the geographic area divisions into business units dedicated to a specific function or product. Over the next twenty years, IP proceeded to make significant capital changes...

Why would a three- layer model of communication that has the layers physical, network, and application be insufficient to adequately describe network communication? 2. What is the history of the OSI reference model? How did it come about and why was it created? ` 3. What is the history of the TCP/ IP model? Why was it created? TCP/IP has two different names that come from. These key protocols two are usually considered the most important. The internet Protocol is the primary OSI network layer protocol that provides addressing, Datagram routing and other functions in a network. They were developed together with TCP/IP providing the mechanism for implanting the internet.

...Chinese Law The legal history of china started with the Tang Code that was invented around 619 AD to 906, it contained a structure of laws for punishments and crimes but this code was very much a militarist law code seeing the historical time of that era was militarist in nature. It has subsequently been developing and advancing the rules which were seen in the in the Qin Dynasty which was in 221-206 BC which gave in an insight into a structured and advanced legal system. China has culturally been at the centre of many western studies because so much of china has remained unknown to the rest of the western world. This was brought up subsequently studying Chinese law and being asked ‘what is china and what is your image and view of these people’. This question given by Mr Ken Shao showed the class that none of the students had any idea of what china really was. In one instance there was an image of a traditional family and on the other a communist militarist dictatorship, this was only because there was very little information on China and that China was very much the unknown to many countries. The history of China is shown to display that this country has been a highly progressive country within the scope of law but also being one of the slowest countries to implement Intellectual Property Law which has sparked an interest into where the progression in the legal system relating to Intellectual Property Law went into disrepute and the arrival of Intellectual Property Law within...

...(CPU) uses RAM like people g ( ) p p use notepad Stores binary value so can use it later Can read data from RAM to recall value stored earlier CPU sends electrical signal over bus (electrical pathway) to communicate with RAM 4 Random Access Memory (RAM) (cont.) RAM uses address for each unique memory location where byte can be stored To write to RAM: CPU sends signal to RAM over the bus g to write (store) value into byte of RAM Address in RAM Value to be written To read from RAM: CPU uses similar process (see example in Figure 1-3 on next slide) 5 CPU Reads Byte 4 from RAM The CPU uses the same bus to read the current value of a byte in RAM as it does to send a message to RAM. The read request lists the address of the particular byte, asking for its value. RAM returns the binary value stored at that address. CPU Reads Byte 4 from RAM 6 Figure 1-3 Writing Individual Bits in Byte 4 of RAM RAM circuitry sends a slightly different electrical input to the bits that need to store a 1 versus a 0 to control the capacitors . Essentially, RAM chooses one of two inputs to each bit, which results in either a full or partial charge in the capacitor, which in turn represents either a 1 or 0, respectively.

The Internet is being used by its clients to access both static and dynamic data residing on remote servers. In the client-server interaction, the client asks the server to provide information, and, in addition, the server may also request that clients provide information such as in “web forms.” Therefore, the Internet is being used for many different purposes which also include the web servers collecting the information from the clients. Consequently, attacks on the web servers have been increasing over the years. Due to the fact that web servers are now...

...on the TCP/IP security. As we have seen the transmission of data as securely as possible has become top on the list for many companies and persons. As we have begun using the Internet more and more to conduct business remotely, we need to ensure that our most sacred data is protected from harm. To ensure that we understand the transmission of data using TCP/IP, I will explain the history of the protocol and the reason for this being the established standard used. As we have read and know it is a combination of two known protocols that were combined to become one. The Transport Control Protocol is used to ensure successful delivery of data. It carries the destination and source information such as the address for both. The IP protocol or Internet Protocol is the second. This protocol is only for sending data. It combined with TCP will ensure that the data is transmitted successfully. When the protocols began to communicate they can use on of many ways to ensure successful communication. One being the hand shake method. There are more than one and will be explained in the paper. With that transmission come the possibility of interference and high jacking of data. One common discussed security hole is the prediction of the send sequence. There is also the SYN and FIN scanning, which each attack. Then there is UDP security concerns, which an attacker uses empty UDP ports to send datagram’s. These are just a few ways there are security holes defined with using TCP/IP and I will...
