Protocol Explorer, down to the byte
An interactive guide to 33 internet protocols, with animated exchanges and packet fields decoded in context.
- For
- Networking students and protocol learners
- Worth noticing
- Its scenarios are explicitly scripted teaching examples, not live captures; RFC links identify the standards behind each lesson.
Field notes
Lessons are scripted exchanges lasting four to seven events, with play, pause, stepping, and speed controls. A synchronized capture table and byte-level inspector connect visible fields to protocol layers; encrypted or random bytes are marked as unavailable. The directory links 33 protocol topics to primary specifications, while Network and Sequence views offer different ways to follow the conversation. Full lessons beyond the four free protocols and the complete inspector require the one-time Pro purchase.
