Commend International GmbH — 3 prefixes (MA-L)

A MAC address starting with BC:6A:44, 2C:2D:48, or 00:0C:AB belongs to Commend International GmbH, an Austrian manufacturer typically seen on IP-based intercom and critical-communication hardware — audio/video door stations, master stations, and servers deployed in tunnels, hospitals, transit systems, and other public-safety infrastructure.

Commend International GmbH is headquartered in Salzburg, Austria, founded in 1971, and now sits inside the Commend Group (a subsidiary of TKH Group N.V.) with roughly 600 employees. The company holds three confirmed IEEE MA-L (/24) blocks under this identical registered name and address, all traced directly in the project's cached IEEE registry copy — not merely a single bare registration.

The device class is corroborated independently of the OUI registry itself: CISA ICS advisory ICSA-24-051-01 (2024-02-20) documents two vulnerabilities — CVE-2024-22182 and CVE-2024-21767 — in the Commend WS203VICM IP video door station, matching the intercom/door-station hardware line these prefixes are expected to appear on.

IEEE's public OUI data publishes no registration or assignment date for any of the three blocks. Third-party aggregators (e.g. maclookup.app, hwaddress.com) attach dates to these prefixes, but those are database-scrape artifacts, not IEEE facts, and are not recorded here as registration dates.

Registration date

Unknown for all three blocks — IEEE's public OUI data (the IEEE MA-L registry: Registry, Assignment, Organization Name, Organization Address) publishes no assignment/registration date; third-party aggregators (maclookup.app, hwaddress.com) attach dates to these prefixes but these are database-scrape artifacts, not IEEE facts.

Analyst note

Three MA-L blocks plus an independently corroborated product line (IP intercom/door-station hardware, CISA-documented CVEs against a named model) place this well above the single-OUI-shell bar — a substantive, identifiable company rather than a bare registry stub.
