24. Consider a router that interconnects three
subnets: Subnet 1, Subnet 2, and Subnet 3.
Suppose all of the interfaces in each of these
three subnets are required to have the prefix
223.1.17/24. Also suppose that Subnet 1 is
required to support up to 62 interfaces, Subnet 2
is to support up to 106 interfaces, and Subnet 3 is
to support up to 15 interfaces. Provide three
network addresses (of the form a.b.c.d/x) that
satisfy these constraints

- Consider a router that interconnects three subnets: Subnet 1, Subnet 2, and Subnet 3. Suppose all of the interfaces in each of these three subnets are required to have the prefix 223.10.128/24. Also suppose that Subnet 1 is required to support at least 50 interfaces, Subnet 2 is to support at least 100 interfaces, and Subnet 3 is to support at least 12 interfaces. Provide three network addresses (of the form a.b.c.d/x) that satisfy these constraints.arrow_forwardWhat three statements are true about network layer addressing? Network layer addressing uses a hierarchy. It uses addresses that are 48 bits in length. It is used by Ethernet switches to make forwarding decisions. It does not support broadcasts. It uses a method by which the network portion of an address can be identified. Network layer addressing identifies each host distinctly.arrow_forwardMoving to the next question prevents changes to this answer.

The original HTTP protocol used TCP/IP as the underlying protocol. For each page, graphic, or applet, a separate TCP connection was constructed, used, and terminated. This caused several problems: one referred to as the elephant and mice problem and two aspects of connection overhead. Describe both problems. Why were separate connections used? Would UDP rather than TCP be a good alternative? What solution would you propose to these problems to improve HTTP performance?arrow_forward

Subnetting a subnet or using variable-length subnet mask (VLSM) was designed to maximize addressing efficiency. You are required to subnet, based on the number of hosts, including router interface and WAN interface and WAN connections for the following scenario: •Toronto: 60 host addresses •Montreal: 28 host addresses •Ottawa: 12 host addresses •Vancouver: 12 host addresses •WAN1: 2 host addresses •WAN2: 2 host addresses •WAN3: 2 host addresses Using the given address block of 192.168.15.0/24, you can design an address scheme for the network to meet its requirements and save potential addresses.
