Assignment 5

Networking

Problem 1: What’s My IP?

  • There are many different websites that allow you to check your external IP address (the one that faces the world). For example:

  • Try to get one of those sites to work. If you have a VPN, check and see that the address listed is different if you are using your VPN.

  • What is your IP address without a VPN? Where does it say you are located?

  • What is your IP address with a VPN? Where does it say you are located?

  • Can you get your IPv6 address from any of the sites? You may have to turn on IPv6 on your operating system.

Problem 2: Undersea cables

Take a look at the Submarine Cable Map, discussed in the seminar. Zoom in to find the cable (or cables) that are closest to where you live. Choose one path on that cable.

  1. What is the name of the cable?
  2. How long is the link you chose?
  3. Where does the cable start and end?
  4. Are there multiple cables that go from the same location?
  5. Look at a location on the end farthest from where you are located. Investigate that location. Why do you think it was chosen to be at that end of the cable?
