Lab 2: 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 the network portion, host portion, and subnet mask. The types of addresses covered include public, private, unicast, and multicast. Required Resources: - Device with Internet access - Optional IPv4 address calculator Step 1: Analyze the table shown below and identify the network portion and host portion of the given IPv4 addresses. IP Address/Prefix | Class | Subnet Mask | Network ID | Host ID ----------------------------------------------------------- 192.168.10.10/24 10.101.99.17/8 209.165.200.227/24 172.31.45.252/16 Step 2: Analyze the table below and list the range of host and broadcast addresses given a network/prefix mask pair. IP Address/Prefix | First Host Address | Last Host Address | Broadcast Address ----------------------------------------------------------------------------- 198.1.10.0/24 10.0.0.0/8 211.2.3.0/24 183.45.0.0/16

In computer networks, each machine is identified through its IP (Internet Protocol) address, which is unique within a network. An address following IPv4 standards has 4 octets separated by dots. An example of an IPv4 address is 192.168.0.1. The octets of this IP address range from 0 to 255, which essentially means that each octet can represent 256 values. The IP addresses are classified into 5 types, and the following table depicts the range of IP addresses each class supports:
Q1. Hierarchical IP Address 1.1 Give a non-network example of hierarchical addressing and discuss how it reduces the amount of work needed in physical delivery. Do not use any example in the book, the postal service, or the telephone network. 1.2 A firm is assigned the network part 128.171. It selects a 10-bit subnet part. a) Draw the bits for the four octets of the IP address of the first host on the first subnet. (Hint: as we don't use all 1 or all 0, the 1st subnet/host is 00...01, while the last subnet/host is 11...10. The number of 1s and 0s in the expression depends on the length of the subnet/host part) b) Convert this answer into dotted decimal notation. c) Draw the bits for the second host on the third subnet. (In binary, 2 is 10, while 3 is 11.) d) Convert this into dotted decimal notation. e) Draw the bits for the last host on the (last number of your ID, if zero, use the one before the last number)th subnet. f) Convert this answer into dotted decimal notation. Q2. Wireshark for Packet Information 2. Visit calstate.edu, login to the system with your ID/password. Use Wireshark to capture this process. Find the packets with the following protocols: 1) TCP 2) UDP 3) HTTP and answer the following questions: a) What's the source/destination IP address? b) What type of protocol is it? c) What are the source and destination port numbers?
