Assignment 9 - IPv4 Pt. 1Subnets Theory [35 marks] Part 1 Each of the questions in this exercise will reference Subnet Mask 1, Subnet Mask 2, or Subnet Mask 3. The values for these masks are based on the last digit of your NAIT student ID number. For example, if your NAIT student ID number is 8998051 then highlight or circle the row in the table where the Last Digit column value is 1. (i.e., you would be working with subnet mask values of 255.192.0.0, 255.255.240.0, and 255.255.255.248) Last Digit 9 8 7 6 5 4 3 2 1 0 Subnet Mask 1 255.192.0.0 255.224.0.0 255.240.0.0 255.248.0.0 255.192.0.0 255.224.0.0 255.240.0.0 255.248.0.0 255.192.0.0 255.224.0.0 Subnet Mask 2 255.255.248.0 255.255.240.0 255.255.224.0 255.255.192.0 255.255.224.0 255.255.192.0 255.255.248.0 255.255.240.0 255.255.240.0 255.255.192.0 Subnet Mask 3 255.255.255.224 255.255.255.192 255.255.255.248 255.255.255.224 255.255.255.248 255.255.255.240 255.255.255.224 255.255.255.192 255.255.255.248 255.255.255.240 1. Given the IP address 95.227.2.199, apply Subnet Mask 1 and answer the following questions. [2 marks] My subnet mask is: a. How many subnets are there in total? b. How many usable host addresses are there for each subnet? 1. Given the IP address 95.227.2.199, apply Subnet Mask 1 and answer the following questions. [2 marks] My subnet mask is: a. How many subnets are there in total? b. How many usable host addresses are there for each subnet? 2. Given the IP address 17.119.47.72, apply Subnet Mask 1 and answer the following questions. [2 marks] My subnet mask is: a. What is the subnet address? b. What is the broadcast address for this subnet? 3. A medium sized printing company has recently leased a class B IP network from their local ISP. The class B network is 156.93.0.0. Apply Subnet Mask 2 and answer the following questions. [4 marks] My subnet mask is: a. What is the CIDR notation subnet mask? b. How many subnets are created by applying this mask? C. How many hosts are there for each subnet (exponential notation is fine i.e. 2 - 2)? d. What is the broadcast address of the third subnet? 4. Given the IP address 187.211.107.30, apply Subnet Mask 3 and answer the following questions. [2 marks] My subnet mask is: a+What is the subnet address? b. What is the broadcast address for this subnet? 5. Direct communication between two hosts (without a router) can only occur if the two hosts are on the same network (i.e., all network bits are identical in both addresses). Using Subnet Mask 3, fill in the following table: [6 marks] My subnet mask is: Host A 131.22.45.253 221.39.117.42 179.90.184.82 193.193.192.191 128.45.0.3 201.49.126.13 Host B 131.22.49.253 221.39.117.62 179.90.215.254 193.193.190.192 128.45.46.205 201.49.126.33 Communicate Directly [Y/N] Part 2 Answer the remaining questions based on the information given in each one. 6. Given the IP address and subnet mask 221.93.45.182/27, answer the following questions. [3 marks] a. What is the subnet address (network address for this subnet)? b. What is the broadcast address for this subnet? C. What is the binary subnet ID of the subnet? Last saved: Thursday, December 03, 2020 7. Given the IP address and subnet mask 198.72.248.116/28, answer the following questions: [3 marks] a. What is the subnet address (network address for this subnet)? b. What is the broadcast address for this subnet? C. Page 2 of 4 What is the binary subnet ID of the subnet? 8. Fill in the following table for the class C network 197.10.56.0: [9 marks] Full Subnet Range (4th octet only) E.g.: 0-64 Subnet binary values 000 001 010 011 100 101 110 111 Subnet mask: Range of IP addresses usable as valid hosts E.g. 197.10.56.5 to 197.10.56.155 9. A small shipping company requires several networks for its 9 departments. They currently have the following class C IP network: 200.34.69.0. Each department may require up to 12 unique IP addresses. With this knowledge, subnet the network so that the company's requirements are met. [4 marks] a. What is the new subnet mask for the network? b. How many subnets does this mask create? c. Will this allow for the company's unique address requirement? How many addresses per subnet? d. What is the broadcast address of the third subnet?
