Protocol Explorer Expands Network Lessons

This is a strong educational devtool update because it turns protocol theory into something developers can inspect and replay, though it remains a teaching simulator rather than a production network analyzer.

• –Network and sequence views connect topology with message order
• –Packet inspection exposes headers, fields, and hexadecimal representations
• –Broad coverage makes it useful for classes, interview preparation, and architecture discussions
• –Synthetic traces simplify reality, so learners should validate details against RFCs or real packet captures
• –Its relevance to AI developers is indirect: it strengthens the networking fundamentals behind APIs, agents, proxies, and distributed systems
