A network contains 2 routers and a number of hosts. Router 1 links with a number of hosts and forms a subnet A, and also links with router 2 and forms a subnet B. Router 2 links with a number of hosts and forms a subnet C, and also links with router 1 and forms a subnet D. (a) Assign network addresses to each of these 4 subnets with the following constraints: • all addresses must be allocated from 167.97.1XY/23 (XY are the last 2 digits of your student ID number in decimal) subnet A should have enough addresses to support 109 interfaces subnet B should have enough addresses to support 24 interfaces subnet C should have enough addresses to support 250 interfaces subnet D should have enough addresses to support 50 interfaces (b) Using your answer in part (a), provide the forwarding tables for each of the 2 routers.

An ISP provider has a network address of 10.10.0.0 with a subnet mask of 255.0.0.0. The company wants to create four sub-networks for the four customers A, B, C and D that would contain A has - 1024 hosts, B has 512 hosts and Chas 256 and D has 128 hosts respectively. Find the following: a. Find CIDR of an ISP provider and Subnet mask of ISP provider b) Find starting address and end address of customer A, Subnet mask and CIDR of A c) Find starting address and end address of Customer B, Subnet mask and CIDR of B d. Find starting address and end address of Customer C, Subnet mask and CIDR of C e. Find starting address and end address of Customer D, Subnet mask and CIDR of C f) Find remaining addresses an ISP provider hold after the allocation.
DATA COMMUNICATION Consider a subnet with prefix 223.1.24.0/24. How to create three subnets from this subnet, so that subnet 1 can support at least 50 interfaces, subnet 2 can support at least 12 interfaces, and subnet 3 can support at least 100 interfaces. Provide three network addresses (of the form a.b.c.d/x) that satisfy these constraints.
q no 5: In the above network diagram, IP and MAC addresses are given for network nodes. Suppose Host1 (Shahid) sends a datagram to Host2 (Khalid). What IP and MAC addresses (source and destination) will be written in IP and Data link layer headers respectively, for the following intermediate points from Host1 to Host2? Host1 to Router1 (R1) Router1 to Router2 (R2) Router2 to Host2
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).…
