Topology

What it does: sweeps the subnet and draws a node map around the local network, with a per-device icon guessed from MAC vendor (OUI) + hostname — switches, routers, APs, printers, phones, servers, cameras, PCs, laptops, IoT, and media players each get a distinct look instead of a plain dot. Scroll to zoom, click-drag to pan, and there's a reset-view button when you get lost. Save a snapshot and reopen it later, or export it as a PNG.

Safe to run: yes (same sweep as Discovery).

Reading results: a quick visual of who's on the segment and what kind of device each one probably is. Compare a saved map against a fresh one to spot what appeared or vanished. An unrecognized vendor just falls back to a generic icon — that's a gap in the offline/online lookup, not necessarily a suspicious device.
