An ISP is granted a block of addresses starting with 129.80.0.0/16. The ISP wants to distribute these blocks to 2600 groups as follows: The first group has 200 medium sized businesses; each need 14 hosts. The second group has 400 small businesses; each need 6 hosts. iii. The third group has 2000 point-to-point links; each need 2 hosts. Design the sub-blocks and give the slash notation for each sub-block. Find out how many addresses are still available after these allocations.
Using https://wiki.dd-wrt.com/wiki/index.php/Linking_Subnets_with_Static_Routes as a base, modify the scenario for VLSM based subnets given the following information. Site address (CIDR Notation) = 192.168.10.0/24 Subnet Included hosts Number of hosts required Subnet ID(CIDR notation) 1 Computer Labs 1 and 2 110 ? 2 Computer Lab 3 60 ?
The usage of static routing has been met with opposition for several reasons, but which of the following is NOT one of them? O. Extra hardware or bandwidth is unnecessary. O.b. The routing tables are modest in size, need just occasional attention. Any alteration to the topology will, of course, have consequences for the setup. The path to the destination never deviates from that one.
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.
Consider the following non-default subnet masks: (a) 255.255.248.0, (b) 255.128.0.0 . To which IP address class do they pertain?Write down the following in CIDR notation: (a) IP: 150.160.170.180, Subnet Mask:255.255.224.0; (b) IP: 75.80.85.90, Subnet Mask: 255.252.0.0 Three stations A, B, C and D are connected to a common Ethernet hub. Their IPaddresses and subnet mask are respectively: 200.100.50.67, 255.255.255.252;200.100.50.7, 255.255.255.248; 200.100.50.138, 255.255.255.240 and 200.100.50.1,255.255.255.254. Determine which among these stations can communicate with eachother. You need to show all detailed workings.
54- A network for a local office requires 4 LAN subnets as follows: · Subnet A - North Office with 31 hosts; · Subnet B - East Office with 15 hosts; and · Subnet C - South Office with 7 hosts. · Subnet D – West Office with 4 hosts. Given the IP Address 192.168.15.0 /24 and above described network requirements: 1. Design an optimal address scheme using Variable Length Subnet Mask (VLSM) method; and What will be the subnet mask of Subnet B?

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
4 LANS are connected to a router (R1) with each LAN compares of several hosts connected to a switch. Each LAN cotains the following number of hosts (end devices and the gateway interface), • LANI à 30 Hosts • LAN2 à 15 Hosts • LAN3 à 20 Hosts • LAN4 à 3 Hosts You have received the address space 200.16.1.0/24. Use the address space to create a subnetting scheme of four subnets with equal size in a way to accommodate the number of hosts required. Consider the following points in your answer, / Explain the procedure of your subnetting scheme / Highlight the suitable prefix and the subnet mask / Highlight the number of wasted hosts in each subnet after determining the most suitable prefix / Use the table below to provide the subnet details for each LAN Subnet Address First Host address Last Host address Broadcast address 1 LANI 2 LAN2 3 LAN3 4 LAN4
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?

Refer to the above topology, 6 subnets are required (i.e, three LANs and three WAN links) and the largest number of host is 50. Starting from the largest host group, efficiently distribute the IP addresses using variable length subnet masks to minimize loss of IPs. Calculate the following for each subnet using 192.168.10.0/24 address. - Subnet and broadcast addresses - Subnet mask Also assign the IPs for each interface of router from the given subnet address range
