NETIO — two distinct IEEE registrants share the "netio" slug

The slug "vendor-netio" is ambiguous: it matches two unrelated IEEE MA-L registrants. The primary, best-documented one is NETIO products a.s., a Prague-based Czech manufacturer of networked smart power devices, holding OUI 24:A4:2C. The second is Netio Technologies Co., Ltd, a Taipei networking-hardware company holding OUI 00:1B:EC. They are separate companies in different countries and should not be conflated. The bulk of this entry covers NETIO products a.s. because it is the entity with a verifiable current product line and public profile. NETIO products a.s. was incorporated in 2016 from a division of KOUKAAM (operating since 2003) and makes the PowerPDU, PowerCable, PowerBox, PowerDIN, and 3-Phase lines — LAN/WiFi power distribution units and smart sockets that do remote per-outlet switching and power metering. Their management surface is broad: an HTTPS web interface plus M2M protocols (JSON API, MQTT-flex, Modbus/TCP, SNMP, XML, Telnet), with UDP-broadcast discovery via the NETIO Discover utility and integration with AV controllers (Crestron, Control4, ELAN, Neets). A 24:A4:2C MAC on a local network indicates a NETIO smart power device, typically found in datacenter racks, server rooms, AV installations, and industrial/smart-building environments. No CVEs were found for NETIO products a.s. in NVD or general web search as of June 2026, but the plaintext Telnet interface and the breadth of exposed M2M APIs are worth flagging as a soft risk for network operators. The critical OUI caveat applies as everywhere: IEEE publishes no registration dates — any "date registered" on a third-party MAC-lookup tool (e.g. maclookup.app shows "28 March 2010" for 24:A4:2C) is a database artifact, not an IEEE fact.

IEEE assignment (primary)

24:A4:2C → NETIO products a.s., U Pily 3, Prague, CZ 143 00 [Confirmed] — IEEE MA-L (oui.csv); maclookup.app/vendors/netio-products-a-s

IEEE assignment (second, distinct registrant)

00:1B:EC → Netio Technologies Co., Ltd, 4F-1 No. 582 Rueiguang Rd., Neihu District, Taipei, TW 11492 [Confirmed] — IEEE MA-L (oui.csv)

Slug ambiguity

"vendor-netio" maps to TWO unrelated IEEE registrants — NETIO products a.s. (CZ, 24:A4:2C) and Netio Technologies Co., Ltd (TW, 00:1B:EC). They are separate entities. [Confirmed] — IEEE oui.csv

Registry / block size

both are MA-L (24-bit OUI, ~16.8M addresses each) [Confirmed] — IEEE MA-L

No MA-M / MA-S match

neither "netio" registrant appears in mam.csv (MA-M) or oui36.csv (MA-S) [Confirmed] — IEEE registry CSVs

IEEE registration date

none published. IEEE's public OUI data contains NO assignment/registration date; any third-party "date registered" (e.g. maclookup.app "28 March 2010" for 24:A4:2C) is a database artifact, not an IEEE fact. [Confirmed for absence; the 2010 value is unverifiable] — maclookup.app/vendors/netio-products-a-s

HQ / country (primary)

Prague, Czech Republic [Confirmed] — netio-products.com/en/about-us

Company background (primary)

Czech joint-stock company incorporated 2016 via acquisition of a KOUKAAM division (operating since 2003); ~10-19 employees (2024); B2B, primarily system integrators [Confirmed] — netio-products.com/en/about-us; emis.com company profile CZ Netio_Products_AS

Company status (primary)

active [Confirmed] — netio-products.com

Device types (primary)

smart networked power devices — PowerPDU (4-8 outlet PDUs), PowerCable (dual-output flat PDUs), PowerBox (compact smart sockets), PowerDIN (DIN-rail units), 3-Phase industrial PDUs; remote power switching + per-outlet metering over LAN/WiFi [Confirmed] — netio-products.com/en; netio-products.com/en/device/powerpdu-4c

Network protocols (primary)

JSON API, MQTT-flex, Modbus/TCP, SNMP, XML, Telnet, HTTPS web UI; UDP-broadcast discovery (NETIO Discover); AV-controller integration (Crestron, Control4, ELAN, Neets) [Confirmed] — netio-products.com/en; netio-products.com/en/software/netio-discover

Security context (primary)

no CVEs found in NVD or web search as of June 2026; attack surface is typical of a networked smart PDU — internet-exposable management UI, multiple M2M APIs, plaintext Telnet, and UDP discovery service [Likely] — netio-products.com/en/device/powerpdu-4c; netio-products.com/en/software/netio-discover

Usage context (primary)

a 24:A4:2C MAC = a NETIO smart power device (PDU / power strip / socket); expected in datacenter racks, server rooms, AV installs, industrial control, and smart-building infrastructure [Confirmed] — netio-products.com/en; gridconnect.com/products/powerpdu-4c-smart-power-distribution-unit

IANA Reference

blank (not applicable to an OUI vendor entry) [Unknown]

Analyst note

resolve which registrant a given MAC belongs to by prefix — 24:A4:2C is NETIO products a.s. (CZ smart-power), 00:1B:EC is Netio Technologies Co., Ltd (TW). Do not merge the two companies in any rendered page.
