SubnetLayer: Learn Protocols Visually

About

SubnetLayer helps users grasp networking protocols with hands-on, packet-based instruction. Moving beyond theoretical explanations or fixed diagrams, students can investigate actual protocol operations, examine packet details, trace every interaction sequentially, and link ideas to applied exercises covering TCP, IP, ARP, ICMP, DNS, DHCP, HTTP, TLS, OSPF, BGP, and other protocols.
