Question 5 The network 200.100.1.0/24 is assigned. We need to put 45 hosts in each subnet. a. How many bits are needed on the host portion of the assigned address to accommodate at least 45 hosts? b. What is the total number of IP addresses that can be used in each subnet? c. What is the maximum number of subnets that could be created?

An IP address can be written as a 32-bit number. For a class B network, the two most significant bits are set to 10. The 16 most significant bits are used as a network ID, and the 16 least significant bits are used as a host ID. However, the host ID cannot be all O's or all 1's. How many hosts (i.e., host IDs) can there be on a class B network? Type your answer.

6. An ISP has the following Routing Table depicting the 7 prefixes he has as customers. What is the smallest number of prefixes he will need to advertise to the outside world announcing reachability to all its customers but no other? If more than one prefix, list them separated by commas (This question is about address aggregation) a. # of Prefixes: b. Prefix (es): 212.56.146.0/24 212.56.147.0/24 212.56.148.0/24 212.56.149.0/24
