1. Suppose you are retrieving your email at the start of a new day at the College and your mail first reaches the BMCC's web server. Assume the BMCC (Borough of Manhattan Community College) webserver does not have the MAC Address of the workstation receiving these mail messages. Explain in detail how the ARP protocol is usedin locating the final destination of the internal network computer that will be receiving this Internet traffic.

2. The conversion from IPv4 to IPv6 Addressing has been completed for about 30% of Internet traffic after 22 years. Explain in detail why the Maximum Transmission Unit (MTU) of Ethernet frames is an obstacle in this conversion (hint: look closely at the TCP and IP headers for IPv4 to IPv6 Addressing).
