METEL s.r.o. — 2 prefixes (MA-L)

METEL s.r.o. is a Czech industrial-networking and security-systems manufacturer founded in 1996 and headquartered at Žižkův kopec 617, 552 03 Česká Skalice, in the Náchod district of the Czech Republic. It holds two IEEE MA-L (24-bit OUI) blocks, AC:B7:4F and 00:23:36, both registered to "METEL s.r.o." at the Česká Skalice address. The company designs and builds in-house: industrial managed Layer-2 switches (PoE/PoE+/PoE++, fiber-capable), IO modules, programmable control units, optical converters, and IP systems for physical-security and automation networks. Its flagship LAN-RING and IPLOG infrastructure lines target critical-infrastructure deployments — security systems, transportation, and industrial automation — with hardening features such as Secure Boot per its product documentation. METEL is ISO 9001 and ISO 27001 certified, advertises NDAA compliance, and reports deployments across 32 countries sold through local system integrators. As an EU-based, NATO-aligned vendor with roughly three decades of operation and no adverse security findings, its OUIs reliably identify genuine METEL industrial-network hardware; note that, as with all IEEE OUI data, no assignment date is published for either block.

IEEE assignment

2 prefixes → METEL s.r.o., Česká Skalice, Náchod, CZ [Confirmed] — IEEE MA-L

Registry / block size

MA-L (24-bit OUI); holds 2 IEEE prefixes [Confirmed] — IEEE the IEEE MA-L registry. NOTE: IEEE's public OUI data publishes NO assignment/registration date (the IEEE MA-L registry columns are only Registry, Assignment, Organization Name, Organization Address); any "date registered" on third-party tools is a database artifact, not an IEEE fact.
