Problem 1: Differentiate between routing and forwarding. Problem 2: Consider a subnet with prefix 192.118.30.128/26. Give an example of one IP address (of form XXX.XXX.XXX.XXX) that can be assigned to this network. Suppose an ISP owns the block of addresses of the form 192.118.30.64/26, and wants to create four subnets from this block, with each block having the same number of IP addresses. What are the prefixes (of form a.b.c.d/x) for the four subnets? Problem 3: DHCP is a client-server protocol. A client is typically a newly arriving host wanting to obtain network configuration information, including an IP address for itself. Describe in details the steps of assigning an IP address for a newly arriving host. Problem 4: An application generates chunks of 40 bytes of data every 20 msec, and each chunk gets encapsulated in a TCP segment and then an IP datagram. What percentage of each datagram will be overhead, and what percentage will be application data
