CISCO. Cisco Networking Academy Mind Wide Open Lab- Identifying IPv4 Addresses Objectives Part 1: Identify IPv4 Addresses Part 2: Classify IPv4 Addresses Background / Scenario In this lab, you will examine the structure of Internet Protocol version 4 (IPV4) addresses. You will identify the various types of IPV4 addresses and the components that help comprise the address, such as network portion, host portion, and subnet mask. Types of addresses covered include public, private, unicast, and multicast. Required Resources · Device with Internet access · Optional: IPv4 address calculator Part 1: Identify IPv4 Addresses In Part 1, you will be given several examples of IPV4 addresses and will complete tables with appropriate information. Step 1: Analyze the table shown below and identify the network portion and host portion of the given IPv4 addresses. The first two rows show examples of how the table should be completed. Key for table: N = all 8 bits for an octet are in the network portion of the address n = a bit in the network portion of the address H = all 8 bits for an octet are in the host portion of the address h = a bit in the host portion of the address Network/Host N,n = Network, H,h = Host IP Address/Prefix Subnet Mask 192.168.10.10/24 N.N.N.H 255.255.255.0 10.101.99.17/23 N.N.nnnnnnnh.H 255.255.254.0 209.165.200.227/27 N.N.N.nnnhhhhh 255.255.255.224 209.165.200.224 172.31.45.252/24 N.N.N.H 255.255.255.0 172.31.45.0 10.1.8.200/26 N.N.N.nnhhhhhh 172.16.117.77/20 N.N.nnnnhhhh.H 255.255.240.0 172.16.112.0 10.1.1.101/25 N.N.N.nhhhhhhh 209.165.202.140/27 192.168.28.45/28 N.N.N.nnnhhhhh 255.255.255.224 209.165.202.128 N.N.N.nnnnhhhh 255.255.255.240 192.168.28.32 Lab- Identifying IPv4 Addresses 255.255.255.192 10.1.8.192 255.255.255.128 10.1.1.0 Network Address 192.168.10.0 10.101.98.0 @ 2020 Cisco and/or its affiliates.

Step 2: Analyze the table below and list the range of host and broadcast addresses given a network/prefix mask pair. The first row shows an example of how the table should be completed. IP Address/Prefix First Host Address Last Host Address 192.168.10.254 Broadcast Address 192.168.10.10/24 192.168.10.1 192.168.10.255 10.101.99.17/23 10.101.98.1 10.101.99.254 10.101.99.255 209.165.200.227/27 209.165.200.225 209.165.200.254 209.165.200.255 172.31.45.252/24 172.31.45.1 172.31.45.254 172.31.45.255 10.1.8.200/26 10.1.8.193 10.1.8.254 10.1.8.255 172.16.117.77/20 172.16.112.1 172.16.127.254 172.16.127.255 10.1.1.101/25 10.1.1.1 10.1.1.126 10.1.1.127 209.165.202.140/27 209.165.202.129 209.165.202.158 209.165.202.159 192.168.28.45/28 192.168.28.33 192.168.28.46 192.168.28.47 Part 2: Classify IPv4 Addresses In Part 2, you will identify and classify several examples of IPV4 addresses. Step 1: Analyze the table shown below and identify the type of address (network, host, multicast, or broadcast address). The first row shows an example of how the table should be completed.
