SubnetLayer: Learn Protocols Visually

什么是 SubnetLayer: Learn Protocols Visually？

SubnetLayer makes networking protocols easier to understand through interactive, packet-level learning. Instead of relying only on theory or static diagrams, learners can explore real protocol flows, inspect packet fields, follow each exchange step by step, and connect concepts with practical labs across TCP, IP, ARP, ICMP, DNS, DHCP, HTTP, TLS, OSPF, BGP, and more.
