MAC / OUI lookup

What it does: turns a MAC address into its vendor (from the OUI), with format variants and flags. Recent lookups show in the right panel; flag one (⚑) to save it to a watchlist of devices of interest.

Safe to run: yes.

Reading results: the vendor hints at what the device is (e.g. a phone, AP, VM, or IoT board). "Locally administered" MACs are often randomized/virtual.
