3. Suppose that the subnet bits below for the following five subnets A-E all come from the beginning of the fourth byte of the IPv4 address; that is, these are subnets of a /24 block. • A: 00 • B: 01 • C: 110 • D: 111 • E: 1010 (a). What are the sizes of each subnet, and the corresponding decimal ranges? Count the addresses with host bits all 0’s or with host bits all 1’s as part of the subnet. (b). How many IPv4 addresses in the class-C block do not belong to any of the subnets A, B, C, D and E? I'm not just looking for the answer- I'm more looking for a walkthrough!

Subnet the following class B IPv4 network into at least 235 subnets. Complete the following table and answer the questions. Given that the network address is 186.100.0.0 with default subnet mask 255.255.0.0. Subnet # Subnet ID First host IP address Last host IP address Broadcast address for the subnet First Subnet Last Subnet How many bits need to be borrowed in order to create at least 235 subnets? What will be the new subnet mask? What will be the new...
For this assignment you will explore subnet addresses, host addresses and direct broadcast addresses. You will be provided an IP addresses and then asked to answer questions related to the IP. In this assignment, first we explain how to find the subnet address for each subnet, the range of host addresses, and the direct broadcast address. Then you will be asked to do a similar exercise by yourself. Assume that you have been assigned the 192.168.1.0/24 network. You need to...
COMPUTER NETWORKS: 1. An organization with a Class B IP address of 128.25.0.0/16 wants eight subnets in its network. There are some legacy routers. Hence, they do not want to use zero and all-ones subnets. a. How many bits are used in each of the following three fields? netID: ______________ subnetID: __________ hostID: _________________ b. Determine the subnet mask that needs to be set in the hosts in dotted decimal notation. Subnet Mask in dotted decimal notation: ¬¬¬¬¬¬¬¬¬¬¬¬¬¬¬_______________________________________ c. ...
A CIDR block extends from 204.206.160.0 to 204.206.175.255. a. How many bits are in the net id? b. How many bits are in the host id? c. What is the mask in slash and binary notation? d. What is the maximum number of valid IP addresses that are available? e. If I want 19 subnets how does the subnet mask change? Show the first 2 in slash notation. f.What is the maximum number of valid IP addresses available per subnet?
Which of the following is the purpose of a subnet mask in a network? (Select all that apply) a. A subnet mask is not necessary when a default gateway is specified. b. A subnet mask is used to differentiate between the network address, the host addresses, and the broadcast address. c. A subnet mask is required only when bits are borrowed on a network. d. A subnet mask is used to determine in which subnet an IP address belongs. e....
A/ Given the following IP address from the Class B address range using the default subnet mask: 100.110.0.0. Your network plan requires no more than 64 hosts on a subnet. When you configure the IP address in Cisco IOS software, which value should you use as the subnet mask? 255.255.0.0 255.255.128.0 255.255.255.128 255.255.255.252 B/ Identify how many valid host addresses can you have on 192.168.27.32 network with a subnet mask of 255.255.255.240. (2^4) - 2 (2^3) – 2 (2^2)...
COMPUTER NETWORKS: 3. Consider an organization that needs 400 IP addresses. The organization has been assigned two blocks Class C addresses. 200.128.64.0 – 200.128.64.255, and 200.128.65.0 – 200.128.65.255. Having obtained these 512 addresses, the organization decided to subnet its address space with 3 bit subnetID. e. Determine the number of subnets possible in this organization. The organization plans to use zero and all-ones subnets. Number of subnets possible: __________________________________________________ f. Determine the number of hosts possible in each subnet. Number...
Consider the topology shown below with following requirements Three subnets A, B, C, should have enough addresses, starting from 192.100.10.0 to support 500 interfaces, 200 interfaces, and 100 interfaces, respectively. Each of subnets, D, E, and F has 32 interfaces. (not required for address assignment.) The IP addresses for three subnets should be assigned continuously, with spacing of power-2, that means, 250 will be rounded to 256, and so on. For each subnet, the assignment should take the form a.b.c.d/x...
