The slug vendor-dolphin-electronics maps to a single IEEE MA-L block, 0C:9F:71, registered to "Dolphin Electronics (DongGuan) Co., Ltd." in Houjie Town, Dongguan, Guangdong, China — a 24-bit OUI covering roughly 16.7 million addresses. This is an OEM/ODM consumer-electronics manufacturer, not a networking vendor: every product traceable to the company through FCC grantee code 2A8JA is a Bluetooth audio accessory — portable Bluetooth speakers, TWS earbuds, wireless earphones, headsets, and neckband headphones — all operating in the 2402–2480 MHz band with no Wi-Fi, Ethernet, or IP-networking radios. The practical asset-classification consequence is that seeing 0C:9F:71 on a network almost always means a Bluetooth peripheral that has paired or bridged onto the LAN, not infrastructure gear. Name disambiguation matters here: at least three other unrelated "Dolphin" organizations hold IEEE registrations — "Dolphin Concepts Limited" (MA-M, 50:FF:99:8x, Hong Kong), "Dolphin Interconnect Solutions AS" (MA-L, 00:12:A5, Norway, a PCI Express/interconnect company), and "Shenzhen Dolphin Electronic Co., Ltd" (MA-L, 00:1D:15) — none of which is this Dongguan vendor. The company has no standalone corporate website; its public footprint is the Global Sources B2B listing plus FCC filings, and it exports under multiple downstream brand names to US distributors. IEEE publishes no registration date for this or any OUI, so none is recorded here.
