NETW202 Week 5 Lab Report

Your Name NETW202, Professor’s Name A. Kaina Current Date 5/31/18 iLab #5: Converting Decimal to Binary and Binary to Decimal (9 points)

Summary Paragraph (3 points):

In this iLab, I learned to convert decimal to binary and binary to decimal. The decimal to binary conversion process shows how to use simple addition to determine which bits are used by employing binary “1” to signify “on” or “0” to signify “off.” Conversely, binary to decimal conversion demonstrates how 1’s and 0’s indicate which bits are needed to determine the corresponding decimal number. This knowledge is beneficial as it aids in understanding the binary aspect of an IP address, which is crucial in networking. Understanding these conversions is directly related to this week’s TCOs, providing a foundational skill set necessary for network addressing and troubleshooting. This skill will be highly valuable in both my academic journey and professional career in IT, where network configuration and management are key components.

Task 1:

Paste two completed decimal-to-binary and two completed binary-to-decimal conversion screenshots below. (1 point each)

119 = 64 + 32 + 16 + 4 + 2 + 1 Decimal is 53

Decimal is 151

Task 2:

What is the binary equivalent of the decimal number 235? Be sure to show your work. (1 point) The binary form of 235 = 11101011

Task 3:

What is the decimal equivalent of the binary number 11011110? Be sure to show your work. (1 point) The decimal is 222 = 128 + 64 + 16 + 8 + 4 + 2

Classifying Network Addressing iLab (14 points)

Summary Paragraph (3 points):

I started out doing the actual conversions on paper and then transferred them to the Excel sheet I created. This process helped me understand the concept and origin of an IP address. I previously struggled with grasping how decimal numbers are converted into binary and vice versa. This lab significantly enhanced my comprehension of how computers communicate between applications. IP source addresses contain 32-bit binary values representing the IPv4 address of the host sending a packet. TCP/IP supports Class A, B, and C addresses that are assigned to hosts, with each class defining the bits used for the network ID and the host ID. This also clarifies the potential number of networks and hosts per network.

Task 1:

Paste two screenshots of completed conversions from IP addresses to decimal formats below. (.6 points each)

Task 2:

Convert the following binary IP address to decimal format and indicate to which class it belongs: 10110100.00100101.00110101.00001010 IP 180.37.53.10

Task 3:

Complete Steps 7–17 iLab questions on the following:

1. Determining an address class, the number of bits in the network ID, and the maximum number of usable hosts
2. Testing your knowledge of host IP addresses, whether they are valid or invalid

Step 7:

200.42.129.16 Address Class: C Network ID bits: /24 Max Number of hosts: 254

Step 8:

14.82.19.54 Address Class: A Network ID bits: /8 Max Number of hosts: 16,777,214

Step 9:

216.27.61.137 Address Class: C Network ID bits: /24 Max Number of hosts: 254

Step 10:

198.53.147.45 Address Class: C Network ID bits: /24 Max Number of hosts: 254

Step 11:

123.45.67.89 Address Class: A Network ID bits: /8 Max Number of hosts: 16,777,214

Step 12: 23.75.345.200 - Invalid

Step 13: 216.27.61.134 - Valid

Step 14: 102.54.94 - Invalid

Step 15: 255.255.255.255 - Invalid

Step 16: 142.179.148.200 - Valid

Step 17: 0.124.0.0 - Invalid

Task 4:

1. Determine the address class, the number of bits in the host portion of the address, and the maximum number of usable hosts for the following IP address: 176.34.56.91 a. Class B___ (.6 points each) b. Bits in the host portion of the address 16_ (.6 points each) c. Maximum usable hosts _ 254____ (.6 points each)

2. Determine whether the following address is a valid host address (and if not, explain why not): 120.0.255.255. (1.2 points) 120.0.255.255 is a valid IP address. It is a Class A address since the first octet “120” is within the range 1–126. However, it is a private IP and is not routable on the Internet because of the 255.255 at the end of the address.

Section II: IPv6

1. Drivers for Transitioning to IPv6 (2 points)

What I understood from this review is the importance of transitioning and implementing IPv6 to eventually replace IPv4 addressing. The document discusses that for IPv6 to work successfully, it must function in a parallel environment with IPv4. The benefits of IPv6 include enhancements for addressing, configuration, performance, mobility, network usage, and support for real-time and multicasting. However, there are potential challenges, including IPv6 penetration, economic factors, migration from IPv4, and security concerns. I agree with the concept of “growing pains” during the proliferation of IPv6, as although there is a desire to implement IPv6 quickly, it is not yet ready to operate independently and still relies on IPv4 support.

2. Enterprise Checklist for IPv6 Readiness (2 points)

My takeaway from this review is that it discusses the benefits of using IPv6 and introduces the NTIA IPv6 readiness tool and drivers for the transition to the new standard. The tool helps companies navigate the transition by providing a structured approach to assess their IPv6 readiness. Like the previous article, this review emphasizes the importance of IPv6 and IPv4 working together in parallel to facilitate a smoother transition. The NTIA IPv6 Readiness Tool serves as a planning template for businesses, enabling them to evaluate their preparedness for IPv6 implementation.

3. IPv6 Readiness (2 points)

This review focuses on market dynamics, market leaders, and market trends concerning IPv6 transitions. While the content is similar to the other articles in discussing the advantages and disadvantages of transitioning to IPv6, this review delves deeper into the IPv6 market, which includes ISPs, website operators, and home router vendors. The article highlights the importance of understanding market forces that influence the adoption of IPv6.

4. Use the NTIA IPv6 reference page at https://www.ntia.doc.gov/page/additional-ipv6-resources: Which document did you select and read (include citation and URL)? (3 points)

The document I chose is the IPv6 Readiness tool. Internet Protocol (IP) is the core network layer protocol upon which the Internet is built. The current version of the protocol, IPv4, has been in use since the origin of the Internet. The document discusses the forthcoming transition from IPv4 to IPv6 and the necessity for businesses to prepare for this shift. https://www.ntia.doc.gov/other-publication/2011/about-ipv6-readiness-tool
