1. What is the name of the last router (or IP address of the last router) before your packets cross the Atlantic Ocean to Europe?

2. What is the name of the first router your packets reach in Europe on their way to university of Crete? The letters in the name usually contain a country code in non US countries. See if you can find one and give me your best guess about what country this router is in.

3. What is the round trip time to the last router before leaving the US? What is the round trip time to the first router outside the US? Based on this, what do you think the propagation delay across the ocean is?

4. Assume it is 6,000 Km across the Atlantic ocean for this link. What do you calculate the propagation delay to be (use 2x108 m/s for propagation speed)? What is the difference between this and your answer in question 11? How do you account for any difference you see?
