IP Addresses and DNS Reflection Questions

IP Addresses and DNS Reflection
Overview
This video features the father of the Internet, Vint Cerf, and Microsoft engineer, Paolo Mejia, addressing the question, “How does data know where to go on the Internet?” They introduce the concepts of Internet Protocol (IP) addresses and the Domain Name System (DNS). In this worksheet, you will use ideas covered in the video as well as search for information on the Internet to answer questions… about the Internet!
Directions
  1. Watch the video, “IP Addresses and DNS.”
  2. Research any additional information required using an Internet search engine.
Questions
  1. What is a protocol?
A protocol is a standard procedure that everyone can follow in order to communicate with each other without any hassle of some sort.
  1. What is an Internet Protocol (IP) address? How is it organized hierarchically?
An Internet Protocol (IP) address is an list of digits that describe your computer like an address to a home. It is organized hierarchically by the country/network, region, subnetwork, and address.
  1. How many bits are in an IPv4 address?  How many IPv4 addresses does that mean there are?
There are 32 bits in an IPv4 address. There are approx. 4 billion address in IPv4 addresses.
  1. What is the difference between IPv6 and IPv4.  Why do we need IPv6?
The difference between IPv6 and IPv4 is that an IPv6 address is larger with 128 bits instead of 32 bits. Instead of 4 billion addresses, there are 340 undecillion addresses in an IPv6 address. We need IPv6 because the internet is growing in popularity and needs more addresses for newer users.
  1. What is an IP packet?
An IP packet is a segment of data that is sent through a network protocol.
  1. What is the difference between an IP address and an IP Packet?
The IP address is the address of a computer that bits and data needs to be sent to. An IP packet is the actual thing that gets sent to an IP address.
  1. What is the purpose of the Domain Name System (DNS)?
The purpose of the Domain Name System (DNS) is that it translates domain names into their IP addresses.
  1. Optional: What is the IP address of the computer you’re sitting at right now?
146.115.11.101

Your public IP address

Reflections from Blown to Bits Ch. 3 (Homework- 9/28/17)

Read Blown to Bits (www.bitsbook.com), Chapter 3 , Ghosts in the Machine, pp. 80-88 (Representation, Reality, and Illusion), then answer the following questions: You can find this under forms and docs/Blown to Bits How does highlighting in a PDF doc work? What are the computational ideas utilized? Continue the exploration of HTML by determining how you would complete today’s activity in HTML. Further compare your own protocol with HTML. Reflections from Blown to Bits Chapter 3: Highlighting in a PDF docs works by using a Highlight tool that will send bits over to the letters and alter the binary. The binary is changed so that when the bits processes through, the letters will be the same but highlighted in a color instead. Between my own protocol and today’s activity, they look pretty similar since they are in the same HTML format. My own protocol was a little less precise about fully doing it in HTML due to being new at the protocol.

Blown to Bits Appendix/Ch.3 Reflection (Homework- 10/11/17)

Day 3: Packets and redundancy Homework due Wednesday, Oct 11: Blown to Bits (www.bitsbook.com), Appendix - The Internet as System and Spirit, pp. 301-309, “The Internet as a Communication System,” then answer the following question: It is interesting to think about the foresight (or luck?) that caused initial Internet designers to choose a packet-switched network as the basis for the Internet. What do you think, foresight or luck? Blown to Bits (www.bitsbook.com), Chapter 3 - Ghosts in the Machine, pp. 91-92, “Data Formats as Public Property,” then answer the following question: What do you think the Internet would be like today if different companies’ network protocols were still competing for adoption for the Internet, instead of TCP being the de facto standard? Blown to Bits Ch.3 Reflection- (by Josh Lim) I believe it is foresight because they were not fully aware on their issues at the time. The designers from the experiments would have trouble understan...
