Problem
1. Why is ARP necessary if every workstation connected to the Internet has a unique IP address?
2. If I connect to the Internet from home, is it likely that my workstation is using DHCP? Explain.
3. If someone on the Internet sends you an e-mail, will NAT delete it before it gets delivered to you? Why, or why not?
4. If three users on one local area network all request a Web page at the same time, how does NAT know which results go to which workstation?
