What you will gain after the course

  • Packet Analysis

  • Protocol

  • TCP/IP

  • Packet structure and fields of each header

Latest version for 2025!
Let's understand networks with pictures and animations!

Networking is easy and intuitive ,
Follow along with the pictures and motion video!

Learn about the roles and flow between TCP/IP and OSI layers.

Learn intuitively and easily with pictures and motions

Let's take a look at some packet headers of important protocols with Wireshark .

Learn more about packets and protocols , and the fields in each header .

This will allow you to extend your learnings by analyzing packets !

You can download the full lecture summary as a PDF !

(about 180+)

What will you learn?

Learn about roles between layers

Learn how each layer interacts with each other and how they are referenced in the network.

Learn about the role of protocols

Learn what roles each layer protocol plays. Let's learn about the working principles of Ethernet, IP, TCP, UDP, QUIC, HTTP, DHCP, and other essential protocols!

Learn about the structure of packets at each layer.

Let's take a closer look at the structure of the Ethernet header, IP header, and TCP header. Let's take a closer look at the structure of each header in the packet and learn what each field in the header does.

Let's analyze the structure and fields of the header through practice.

You can intuitively understand at a glance how the Ethernet header, IP header, and TCP/UDP header that you learned earlier are displayed in Wireshark through tables and figures.

Let's learn about protocol principles .

What is the difference between supplementary textbooks and lectures?

  1. The book is text-centric and refined , while the lectures are animation-centric .
    You may also purchase the book to acquire the lecture content.

  2. The lecture omits contents such as TCP congestion control/flow control and routing protocols such as RIP, OSPF, and BGP (i.e., the contents are included in the book).
    The book omits packet structure and Wireshark practice (i.e., the content is included in the lecture) .

  3. If you are concerned about the cost, I recommend the book to undergraduate students .


Practice environment

  • Please install wireshark in advance!

  • Since the screen is split in half during the practical training, you may experience inconvenience if you take the practical training lecture on a laptop. Therefore, we recommend using a dual monitor for the practical training portion.

Player Knowledge and Notes

  • No prior knowledge required.


  • I recommend that you turn on the subtitles when you study. Unlike the previous lectures, Inflearn has its own subtitle function, so I did not add the subtitles myself. I did re-record it several times, but I recommend Korean subtitles to prevent your pronunciation from being muffled .

Who is this course right for?

  • Undergraduate student who wants to understand networking easily and enjoyably

  • Undergraduates/professionals wanting quick, intuitive understanding over text learning

  • Undergrads/Workers needing a quick network overview & diagrams

    우선 내용부터 말씀 드리면, 학부 수업이 지루하고 잘 이해되지 않는 학부생, 비전공이지만 소프트웨어 개발을 시작한 주니어, 그 외에 부분적으로 모자란 기초 지식을 채우려는 수강자에게 정말 최적의 강의입니다. 그리고 강의 영상의 흐름도 시각적으로 보기 편안하게 구성되어 있습니다. 특히 그림이나 텍스트 내용이 눈에 보기에 피로하지 않고 부드럽게 잘 재생되어 강의를 보는 동안 크게 피로하지 않았습니다. 오랜만에 강의 편안히 잘 듣고 있습니다. 감사합니다.

    이제 초반부 보는데 애니메이션이 들어갔고, 이미지도 깔끔해서 이해하기 편합니다. 내용도 자칫 길 수 있는 내용을 일목요연하게 정리를 잘 해주셔서 따로 정리하는데 힘들지 않아요. 좋은 강의 감사합니다! :D

      안녕하세요, dgh12님! 이전 강에서도 거의 첫 번째로 구매하셔서 수강해주시고 첫 번째로 수강평을 남겨주신 상당히 감사한 분으로 기억하고 있습니다. 나머지 중반부와 후반부도 만족하셨으면 좋겠습니다. 감사합니다, 좋은 하루 되세요!
