# Packet Inspector: DHCP Deep Dive with Wireshark
|
|
|
|
A comprehensive, hands-on course for network engineers and IT professionals who want to master DHCP troubleshooting using Wireshark packet analysis.
|
|
|
|
## Course Overview
|
|
|
|
This course takes you from Wireshark fundamentals through advanced DHCP analysis, covering real-world troubleshooting scenarios that network engineers encounter daily. By the end, you'll be able to capture, filter, and interpret DHCP traffic with confidence.
