PLANET Technology Corporation — 3 prefixes (MA-L)

A MAC address beginning with 00:30:4F, A8:F7:E0, or 50:61:88 belongs to PLANET Technology Corporation, a Taiwan-based networking hardware vendor. These three IEEE MA-L blocks typically show up on managed Ethernet switches, Power over Ethernet gear, industrial and automation switches, fiber media converters, and IP surveillance equipment shipped under the PLANET brand.

PLANET Technology was founded in 1993 and is headquartered at 11F, No. 96, Minquan Road, Xindian District, New Taipei City, Taiwan. The company is active and operating as of 2026, with a current product catalog spanning LAN switching, broadband and wireless LAN gear, IP telephony, IP surveillance, home automation, and network management software.

Unlike a bare single-OUI shell registration, PLANET holds at least three separate MA-L blocks — 00:30:4F, A8:F7:E0, and 50:61:88 — all registered to the same organization and address. Multiple independent assignments plus an identifiable, currently-shipping product line are what distinguish this entry from a one-off IEEE registration with no verifiable substance behind it.

PLANET's currently-shipping firmware has drawn recent security scrutiny. Five 2025 CVEs (CVE-2025-46271 through CVE-2025-46275, CVSS v4 scores of 9.3 or higher) cover OS command injection, hardcoded credentials, and missing authentication in UNI-NMS-Lite, NMS-500, NMS-1000V, and several switch models, disclosed via a CISA ICS advisory and corroborated by independent security researchers. Earlier CVE-2024-8453 and CVE-2024-52558 affected switch firmware as well.

None of PLANET's three OUIs fall within a shared IEEE-administered base such as 70:B3:D5 — each is independently and exclusively assigned to PLANET Technology, so a match on any of the three reliably indicates genuine PLANET hardware. Third-party "registration date" fields shown by lookup tools such as maclookup.app (2000-11-09, 2014-02-25, 2026-03-12 for the three prefixes respectively) are database artifacts, not IEEE facts — IEEE's own the IEEE MA-L registry publishes no assignment-date column at all.
