Philips Hue's IEEE blocks are registered under the legacy name "Philips Lighting BV" at High Tech Campus 45, Eindhoven, Netherlands — a name that no longer matches current branding, since Philips Lighting was spun off from Royal Philips (IPO 2016) and renamed Signify N.V. effective 16 May 2018. The most important device-identification fact: on the IP network, the only Hue device that appears with a Philips/Signify OUI is the Hue Bridge (the IP-connected hub). The Hue bulbs themselves speak Zigbee behind the bridge and do NOT expose IEEE MAC OUIs at L2/L3, so a single OUI hit typically represents an entire lighting deployment rather than many devices. Some Wi-Fi lighting (e.g., the WiZ brand, acquired 2019) may appear under separate registrants. A normalization caution: distinguish the lighting registrant (Philips Lighting BV / Signify) from the general "Philips" / "Koninklijke Philips" (Royal Philips) registrants used for healthcare and consumer electronics — these are different organizations after the 2016 spinoff. For triage, a Philips Lighting/Signify OUI almost always means a Hue Bridge (usually one per home/site).

- Analyst note
- A Philips Lighting/Signify OUI almost always = a Hue Bridge (typically one per home/site); the bulbs are Zigbee and invisible at L2/L3, so one OUI hit usually represents an entire lighting deployment.
