Free browser network simulator adds more real network behavior

NetworkSim is a free network that runs in a browser. It lets people draw a network layout and check whether traffic can actually reach its destination, instead of only making a static diagram.

New features include DHCP, , , port , STP, routing, and other related network behavior. It also adds advanced courses and step-by-step learning tasks for these topics.

The tool still runs fully in the browser, with no signup and no ads. It is still being improved, with feedback requested on confusing parts, missing features, and what should come next.
