1. The Hop Limit field in IPv6 is 8 bits long (the same size as the equivalent Time to Live field in IPv4). Since this hop count is reduced each time an IP datagram enters a router, what are the implications of a small field size?
2. Suppose there is a small commercial retail building in your town that has essentially one room. On one side of the room is a real estate agency and on the other side of the room is a guy who sells tea. How does this situation serve as an analogy for the concept of IP addresses with TCP port numbers?
