GopherTec Inc. — 2 prefixes (MA-L)

A MAC address starting with 00:0F:EC or 84:AF:1F belongs to GopherTec Inc., a Japanese embedded-systems design and manufacturing house, and typically identifies a CPU board, FPGA board, or panel PC rather than a consumer router or IoT gadget.

GopherTec holds two separate IEEE MA-L assignments — 00:0F:EC and 84:AF:1F — both registered to the identical address in Okayama, Japan. Two independent 24-bit blocks under one registrant, plus a documented product line, is more substance than a single bare OUI stub carries.

The company (株式会社ゴフェルテック) was established 3 December 2015, with ¥60 million capital and 33 employees. It builds contract hardware for defense, railroad, medical, industrial-automation, telecom, and broadcast customers — CPU boards on Intel Atom/Core Ultra/Xeon, AMD Xilinx and Intel Cyclone FPGA boards, sensor modules, 10BASE-T1L/T1S and CAN-Wi-Fi converters, LiFePO4 UPS units, and network I/O systems.

A data-quality trap worth flagging: maclookup.app lists an "initial registration" of 03 April 2004 for 00:0F:EC, which predates GopherTec's own stated 2015 founding by over a decade. IEEE's public the IEEE MA-L registry has no date column at all, so that figure is a third-party database artifact, not an IEEE-sourced fact, and should not be treated as this vendor's true assignment date.

Analyst note

A MAC on 00:0F:EC or 84:AF:1F identifies genuine GopherTec-manufactured embedded hardware (board computers, FPGA boards, panel PCs); these are ordinary single-registrant /24s, not sub-allocations of a shared IEEE base, so the identification applies to the full block for each prefix.
