Please just make up random IP address for example sake.

1. Changing IP Addresses (12 pts) Each of your internet capable devices has a different IP address - and, in fact, your laptop (or tablet) receives a new IP address whenever it accesses the internet through different providers. In this problem, you'll sample some of the many IP addresses that identify "you" during the day. Whenever you're asked to determine the IP address use the website whatsmyipaddress.com (or something like it). Grab your internet-enabled phone (if you don't have one, find someone who does). Turn the phone's wi- fi off so that the phone is accessing the internet through the cell provider. Record the IP address and ISP of the phone as IP1. Now log the phone onto a wi-fi network. Record the IP address and ISP of the phone as IP2. Finally, turn the wi-fi off so that the phone is, again, accessing the internet through the cell provider. Record the IP address and ISP of the phone as IP3. (3 pts) Why did the IP address of the phone change when you changed its connection to wifi? Be precise - where is the IP address coming from? What does it mean that the IP address changed? (4 pts) Suppose your computer sent a request for Google's homepage (think TCP protocol) JUST before you toggled your wifi. Would you receive Google's response? Using a diagram (like the very first one we looked at in class) illustrate and explain why or why not Google's response will reach you. (6 pts)
