a2i marketing center — 00-12-41 (MA-L)

a2i marketing center holds a single IEEE MA-L block, OUI 00-12-41, registered to a commercial address in Seocho-gu, Seoul, South Korea (1024-4 Duksan Bldg, Bangbaedong, Seocho-gu, Seoul 137-060). An MA-L assignment is the standard 24-bit block, so 00:12:41:00:00:00 through 00:12:41:FF:FF:FF — roughly 16 million addresses — all resolve to this one organization. Beyond the registry record, almost nothing is corroborable. The organization name reads like a marketing or distribution intermediary rather than a direct hardware manufacturer, but that inference cannot be confirmed: no official website, product line, datasheet, or device-scan sighting could be located in any source. (The US firm at a2ienterpriseinc.com is an unrelated Austin, Texas direct-marketing company and should not be conflated with this Seoul entity.) Device type is therefore Unknown rather than guessed. No security advisories, CVEs, or threat-intelligence reports associate this prefix with malicious or anomalous activity. Worth flagging for any downstream page: third-party MAC databases display a "registered 02 September 2004" date for this prefix, but IEEE publishes no OUI assignment dates — that figure is a database artifact and must not be presented as an IEEE registration date.

Analyst note

A globally-administered 00-12-41 address identifies hardware registered to this Seoul organization, but with no confirmed product line or website the actual device type behind the block cannot be established from public data.
