1. An organization is granted the IP address block 192.168.0.0/16. The administrator wants to create subnets with varying sizes to accommodate different departments. Design a subnetting scheme that creates subnets with the following sizes: Subnet 1: 1000 addresses Subnet 2: 500 addresses Subnet 3: 250 addresses Determine the subnet prefix lengths for each subnet. Determine the subnet masks for each subnet. i) ii) iii) iv) Find the first and last addresses in each subnet. Find the total unused addresses for the whole block.

8. Design 8 subnets for a company with the site address 201.75.38.0. a) What is the network mask? b) What is the subnet mask? c) How many hosts (addresses) can be supported on each subnet? d) What is the address of the 5th subnet?
• IPV6 addresses use 128 bits to represent an address which includes bits to be used for subnetting. The second half of the address (least significant 64 bits) is always used for hosts only. Therefore, there is no compromise if we subnet the network. Use the Figure below to Create five subnets using route prefix 2001:db:acad::/48 (1 Marks) Routing Prefix Subnet ID Interface ID 48 Bits 16 Bits 64 Bits
An organization is granted the block 191.168.0.0/16. The administrator wants to create 500 fixed-length subnets. Find: a) the subnet mask. b) first and the last address in the first subnet. c) number of addresses in each subnet. d) first and the last address in the last subnet (subnet 500)
B. Given a block of IP addresses represented by 192.168.200.0/24, you are being asked to create one subnetwork of 120 hosts, 2nd of 63 host, and third of 16 hosts. Based on concepts of subnetting, write the missing information in following table: 120 Hosts Subnet Subnet Mask 63 Hosts Subnet 16 Hosts Subnet Subnet Mask Subnet Mask Subnet Address Subnet Address Subnet Address 1 Usable Host IP 1st Usable Host IP 1st Usable Host IP Broadcast Broadcast Broadcast address address address
An organization is granted the block 108.153.200.40/17. The administrator wants to create 100 subnets. What is the number of addresses in each subnet assuming that the number of addresses in each block is divided evenly among the subnets?
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.

Given the network address 148.211.93.128/25, develop a scheme for 3 subnets with at most 10 hosts each. Show the subnet mask and CIDR notation for the subnet scheme. Show the 1st, 2nd, and 3rd subnet addresses and list the range of available IP addresses for each subnet.
3) Suppose a host transmits a 3500 byte IP packet over a link with an MTU of 500 bytes. Assuming that IP header does not contain any options, indicate the length (in bytes), more flag, and offset field values (specify the offset values in units of 8 bytes) of the fragments transmitted over the link in the table below. Fragment Length Offset Flag 1 3 4 7 8.
Cisco Router A Network with id: 192.168.0.0 and subnet mask 255.255.0.0 is given to you to split it in such a way that the following classrooms are given adequate number of IPs based on their needs.
