...Unit 3 Assignment: IPv6 Addressing Cuneo, Thomas / NT1230 4-5-13 Research the following organizations and explain their involvement with the internet public IP addresses. a. American Registry for Internet Numbers (ARIN): The non-profit corporation responsible for managing internet number resources (IPv4 and IPv6 addresses). The need for this organization is due to the internet addresses being unique and limited there is a need for some control and allocate address number blocks. b. Internet Assigned Numbers Authority (IANA): This entity oversees global IP address location, autonomous system number location, root zone management in the Domain Name System (DNS), media types, and other Internet Protocol related symbols and numbers. This department is also operated by the Internet Corporation for Assigned Names and Numbers (ICANN). c. Asia Pacific Network Information Center (APNIC): Organization that manages the assignment of the Internet number resources within the Asian continent. They also set the rules and regulations/standards that all designated organizations must abide by and implement. One of their purposes is to provide standard-based inter-networking methods for IPv4 and IPv6 across such networks as Ethernet and so forth. 1. How many IPv4 addresses are possible? There are approx. 4,294,967,295 (4.3 billion) 2. How many IPv6 addresses are possible? There are about 3.4x10^38 (18 quintillion) 3. Why do you think the world is running out of IPv4 addresses?

The internet really started in the 70s as a DARPA research project. At the time, there were 60 or so institutions expected to connect. As the interested research community grew, the addressing scheme was expanded from 8 bits (256 addresses in the predecessor to Internet Protocol (IP) known as Network Control Protocol (NCP)) to 32 bits (the IPv4 addresses we have today). At the time, it was still expected that the internet would serve largely defense, research, and educational institutions. It was essentially a laboratory experiment on a really large...

...Unit 3. Assignment 1. IPv6 Addressing 1a. The American Registry for Internet Numbers (ARIN) is the nonprofit corporation responsible for managing Internet number resources (IPv4 and IPv6 addresses and Autonomous System Numbers) for Canada, many Caribbean and North Atlantic islands and the United States. The Internet addresses must be unique and because address space on the Internet is limited, there is a need for some organization to control and allocate address number blocks. IP address management was formerly a responsibility of the Internet Assigned Numbers Authority (IANA), which contracted with Network Solutions Inc. for the actual services. b. IANA (Internet Assigned Numbers Authority) is the organization under the Internet Architecture Board (IAB) of the Internet Society that, under a contract from the U.S. government, it has overseen the allocation of Internet Protocol addresses to Internet service providers (ISPs). IANA also has had responsibility for the registry for any for Internet operation. c.

Ping, DNS lookup, traceroute utilities, and, Internet Explorer, the web browser are primary tools that come equiped in Windows. The DOS or MSDOS allow use of ping and traceroute specifically, these utilities allow for network mapping and network address or IP address identification, as well as port information. 2. The differences in the organizations are coverage areas. IANA covers the resources delegated to the other organizations (IANA, N,d,). ARIN is delegated to cover the regions of United States, Canada, several parts of the Caribbean region, and Antarctica. RIPE covers northern parts of Asia, Northern Africa, Europe, and Middle Eastern countries. 3. Sam Spade includes tools that can run WhoIs, HTML source code retrieval, trace route, ping, finger, and nslookup. These functions allow retrieval of data from network traffic, electronic mail headers, and identify origins of addresses. 4 Trace route does exactly as the name states, it traces the route of packets back to the originator. This is useful in finding different jump points and pathways to the targeted website, It traces the routes packets take from the user to the target. It shows a route by hops. They target the host address. 5. WhoIs provides general data such as address or domain owner, contact information for owner, and linked sites to a domain...

...Chapter-1 1.0 Introduction With the tremendous advancement of Internet, different aspects of it are achieving the highest peak of growth. An example of it is e-commerce. More and more computers get connected to the Internet, wireless devices and networks are booming and sooner or later, nearly every electronic device may have its own IP address. The complexity of networks is increasing, the software on devices gets more sophisticated and user friendly – interacting with other devices and people are a main issues. At the same time, the complexity of the involved software grows, life cycles are getting shorter and maintaining high quality is difficult. Most users want (or need) to have access to information from all over the world around the clock. Highly interconnected devices which have access to the global network are the consequence. As a result, privacy and security concerns are getting more important. In a word, information is money. There is a serious need to limit access to personal or confidential information – access controls are needed. Unfortunately most software is not bug free due to their complexity or carelessness of their inventors. Some bugs may have a serious impact on the access controls in place or may even open up some unintended backdoors. Security therefore is a hot topic and quite some effort is spent in securing services, systems and networks. On the internet, there is a silent war going on between the good and the bad guys – between the ones...
