Part 4 Deep Packet Analysis of Common Protocols

Once you understand the basic protocols of the TCP/IP suite, it’s time to conduct a deep packet analysis of commonly used protocols – HTTP, DNS, DHCP, and ARP. We’ll examine the header formats and field values of each protocol in detail, along with common options that can be used to facilitate the exchange of data.

The following chapters will be covered under this section:

• Chapter 13, Diving into DNS
• Chapter 14, Examining DHCP
• Chapter 15, Decoding HTTP
• Chapter 16, Understanding ARP
