http://subnetcalculator.info/CIDR-tutorial Lab Assignment: You have been sent from Asgard Galactic Networks and are responsible for providing network administration for the Wakanda autonomous network. Although it has long been an isolated network, with its own protocols, the monarchy recently decided to establish a connection to the Galactic Internet and adopt TCP/IP protocols. Through international arrangement, the subnet block 224.151.60.176/28 has been provided for you to use as public IP addresses in connecting to a tier 1 service on an Internet exchange point (IXP). Use this template to write-in your answers (adjust spacing as necessary) Challenge #1: Identify 10 public IP addresses to be assigned to the external ports of the gateway routers which head the following internal Wakanda sub-networks: Bast network, used for cultural archiving/publication and general purpose computing Ghekre network, used for cultural archiving/publication and general purpose computing Sekmet network, used for cultural archiving/publication and general purpose computing Sobek network, used for cultural archiving/publication and general purpose computing Dora Milaie network, used for security monitoring and general purpose computing T'Challa network, used for command and control and general purpose computing Shuri network, used for technology research and general purpose computing W'Kabi network, used for intelligence, military planning and general purpose computing Nakia network, used for international outreach and general purpose computing Zuri network, used for biomedical research and general purpose computing Hints: 1. 2. Block 224.151.60.176/28 utilizes a subnet mask of 28 bits (/28 in the CIDR address) This means your subnet mask will use the first 28 bits as in: or 255 255 255 240 (in dot decimal notation) 3. Thus, there are 4 bits left for host addressing 11ll 1111.1111 111L1111 111L 1111 0000), allowing 2- 214 host addresses available. 4. What are the next 10 available public IP addresses that can be assigned to the Wakanda sub-network gateway routers in chronological order? Fill Table 1 below. The Bast and Ghekrejaddresses are given to you. Binary notation Decimal notation Description PAdddres 10110000 176 Block network IP address 224.151.60.176 10110001 Bast network IP address 224.151.60.177 10110010 178 Ghekre network IP address 224.151.60.178 Sekmet network IP address Sobek network IP address Dora Milaje network IP address TChalla network IP address Sburinetwork IP address W'Kabi network IP address Nakia network IP address Zuri network IP address Table 1: Public network IP address for each of the subnetworks. In the previous page, you identified the outward facing IP addresses for each of the subnets. The Wakanda sub- network gateway routers, however, will be configured as NAT firewalls to enable the use of private IP addresses within the sub-networks. Each of the Wakanda sub-networks is assigned a different block of private IP addresses. The internal port of each gateway router is assigned the first available host address. The Bast network private IP address block is 172.17.0.0/16 The Ghekre network private IP address block is 172.18.0.0/16 The Sekmet network private IP address block is 172.19.0.0/16 The Sobek network private IP address block is 172.20.0.0/16 The Dora Milaje network private IP address block is 172.21.0.0/16 The T'Challa network private IP address block is 172.22.0.0/16 The Shuri network private IP address block is 172.23.0.0/16 The W'Kabi network private IP address block is 172.24.0.0/16 The Nakia network private IP address block is 172.25.0.0/16 The Zurinetwork private IP address block is 172.26.0.0/16 Challenge#2:For each of the Wakanda sub-networks, identify the subnet mask needed to provide the number of subnets while maximizing the addressable hosts on the subnets. The Bast network requires 3 subnets (two data centers and a client network) The Ghekre network requires 3 subnets (two data centers and a client network) The Sekmet network requires 3 subnets (two data centers and a client network) The Sobek network requires 3 subnets (two data centers and a client network) The Dora Milaje network requires 6 subnets (one data center and five separate client networks) The TiChalla network requires 2 subnets (one data center and a client network) The Shuri network requires 8 subnets (two data centers, five lab environments and a client network) The W'Kabi network requires 4 subnets (two data centers, an operations center and a client network) The Nakia network requires 3 subnets (two data centers and a client network) The Zurinetwork requires 5 subnets (three data centers and two client networks) Hints: 1. The subnet mask for each Wakanda sub-network (from the /16 in the CIDR block assignment) is 2. A subnet mask like this gives you 16 bits (the last 16 zeroes) as available host addresses. But, actually only 216-2 will be given as network address and the last will be the broadcast address. You want to maximize the total number of usable host addresses when you start subnetting. Thus, you will need to start "splitting the pie" of-65K available addresses depending on the number of subnetworks you need to create. 65,534 "usable" host addresses are available, there is a "minus 2 "because the first address 3. 4. To create 2 subnets, you will need 1 bit in the subnet mask 255.255.{10000000.00000000} or 5. To create 4 subnets, you will need 2 bits in the subnet mask 255.255.{11000000.00000000 or 6. To create 8 subnets, you will need 3 bits in the subnet mask 255.255.{11100000.00000000 or 7. And so on. 255.255.128.0000 giving you 215-2 32,776 usable addresses for each subnet. 255.255.192.0000 giving you 214-2- 16,382 usable addresses for eachsubnet. 255.255.224.0000 giving you 228,192 usable addresses for each subnet 13 No. of No. ofName of Netw ork Subnet Mask in Binary Notation Subnets Bits Required Subnet Mask in Decimal Notation 255.255.1100 0000.0 or Bast 255.255.192.0 Ghekre Sekhmet Sobek Dora Milai
