Consider the following diagram: A,B,C and D are subnets, R1, R2, and R3 are routers. Default signifies theentire rest of the internet. All 4 subnets each contain the same number of hosts.Consider the following routing table at R3: CIDR Mask Link 0.0.0.0/0 L4 128.4.6.0/24 L3 128.4.8.0/24 L5 1. If 128.4.6.0 is in A, what is the routing table at R1? 2. The ISP that owns all these networks is short on IP addresses, so theyuse a NAT router for R2. How many public IP addresses will C andD use together assuming they use as many private 10.X IP addresses asthey can? How many total public IP addresses will be used by the entirenetwork? Why doesn’t the ISP care about how many private IP addressesare used? 3. Fix R3’s routing table now that we are using NAT: 4. A node in C is given the IP address 10.0.0.1 and only sends and receivespackets on port 1234. A packet destined for this node reaches R2 witha source of (IP=128.4.6.6, Port=3000) and destination of (IP=128.4.8.0,Port=10000).…

This is Networking subject, Variable length subnet mask (VLSM) subnetting in IPv4. Problem: Given the class B network of 172.30.0.0/16, Subnet fhe networking in order to create the network in figure below with the host requirements shown using the VLSM by preparing a complete IPv4 address. Solution: a. Required hosts per subnet arranged from largest to smallest host. b. Required H bits for each subnet. c. Required H bits to be assigned as borrowed bits per subnet, increment, prefix length, and subnet mask address. d. IPv4 address summary table using VLSM
Assign network addresses to each of these six subnets,with the following constraints: All addresses must be allocated from 212.10.8/23; Subnets A, B, and C should have enough addresses to support 120, 240, and 120 interfaces respectively. Of course, subnets D, E, and F should each be able to support two interfaces. For each subnet, the assignment should take the form of a.b.c.d/x or a.b.c.d/x - e.f.g.h/y. ----- Using your answer to the previous part, provide the forwarding tables (using longest prefix matching) for each of the three routers. You may use label R1A to denote the interface on router R1 that is part of subnet A and so on.

Consider a web page whose base file is of size S1 = 10 KB. Assume that the web page consists of N = 20 inline objects each of size S2 = 100 KB. Assume that the round-trip time to the web server is T = 100 ms and the bottleneck capacity is C = 10 Mbps. Ignore any packetization delays and header overhead.a. Assuming non-persistent HTTP is used with a single TCP connection, how long does it take to download the web page?b. Assuming non-persistent HTTP is used with 4 parallel TCP connections, how long does it take to download the web page?c. Assuming pipelined, persistent HTTP is used, how long does it take to download the web page? ”Pipelined” means requests for multiple objects can be sent back-to-back on the same connection.d. Assuming non-pipelined, persistent HTTP with 2 parallel TCP connections is used, how long does it take to download the web page? Assume that the 2 parallel connections equally share the total available bandwidth C.
21.) Consider the following configuration. Computer “A” IP address: 172.16.100.100 Subnet mask: 255.255.0.0 Computer “B” IP address: 172.16.200.200 Subnet mask: /16 What should be done to allow these computers to send and receive data to and from each other? A.) Nothing needs to be changed. B.) Delete the subnet mask from each computer. C.) A router must be configured and placed between the two computers. D.) Remove the hub between the two computers and replace it with a switch.
In this exercise, we estimate the CIDR address block requirements for TrendyWidgets Inc. For example, if TrendyWidgets needs about 8,000 IP addresses, you would say that TrendyWidgets needs a /19 CIDR block. This is because a /19 address block uses 19 bits for the network part of the IP address, leaving 32 – 19 = 13 bits available for the host part. This allows unique labeling for 213 = 8,192 hosts. Answer the following questions: 1. If each computer on TrendyWidgets’ network is allocated an IP address, how many IP addresses is TrendyWidgets likely to need? 2. Based on this estimate, what is a CIDR address-block size suitable for TrendyWidgets?
