Module 7
Practical Network Analysis
1
Packet Analysis: Unpacking a Web Request
Capture and analyze a basic web request using `tcpdump` or Wireshark to identify the roles of Ethernet, IP, TCP, and DNS.
2
IP Addressing Fundamentals
Design an IP addressing scheme for a small network using a given CIDR block and assign valid addresses to hosts.
3
DNS Resolution with `dig`
Trace the path of a DNS lookup using `dig` and explain each step of the resolution process.
Decoding DHCP: A DORA Dive
Observe a DHCP lease assignment on a network and identify the DORA process steps in a packet capture.
TCP vs. UDP: Analyzing Network Traffic
Analyze network traffic to determine if an application uses TCP or UDP and explain the reason for the choice.
6
Exploring the ARP Table: IP to MAC Address Resolution
Inspect the ARP table on a Linux system and trace how an IP address is mapped to a MAC address on the local network.
7
Network Topology and Redundancy Analysis
Analyze a network diagram to identify its topology (e.g., star, leaf-spine) and evaluate its redundancy.
8
Hub, Switch, and Router: Understanding Traffic Forwarding
Differentiate between a hub, switch, and router by observing their traffic forwarding behavior in a simulated network.
