LG Information & Comm. — 2 prefixes (MA-L)

A MAC address beginning with 00:12:56 or 00:19:A1 belongs to LG INFORMATION & COMM., a former LG Group subsidiary that built PBX/telecom switching systems, network transmission and satellite communications gear, CDMA mobile network equipment, and Freeway/Cyon-branded mobile handsets before merging into LG Electronics in 2000.

The registrant traces to Daehan Semiconductor (1976, spun out of Daehan Electric Wire), later Goldstar Semiconductor, which grew into LG Information & Communications Co., Ltd. (LG정보통신) — LG's telecom and mobile-equipment arm. It merged into LG Electronics on 2000-09-01, with the handset line becoming LG Electronics' Mobile Communications division. This history comes from a Korean-language community wiki (Namu Wiki), a secondary rather than primary source, so it is tagged Likely rather than Confirmed.

Both prefixes carry the identical registrant string and near-identical Seoul addresses (Kasan-dong, Kumchon-gu) across the project's IEEE OUI mirror, the Wireshark the Wireshark manufacturer database, and maclookup.app — three independently-agreeing sources, which is why this consolidated vendor entry clears the abstention bar for a bare single-OUI shell. No live network-scan sightings of either prefix were found; one AI-search-synthesis result mis-attributed 00:19:A1 to Cisco, which contradicts all three registry sources above and is disregarded as a search-engine error.

maclookup.app shows per-prefix "Registration Date" values (2004-09-09, 2006-09-25) that postdate the 2000 merger by several years — a sign these are third-party scrape timestamps, not IEEE assignment dates. IEEE's public OUI data publishes no registration dates at all, so a device carrying this OUI today is most plausibly either surviving legacy PBX/telephony hardware or a stale vendor-string artifact from an OUI assignee that stopped existing independently a quarter-century ago.

IEEE assignment

Registry / block size

MA-L (24-bit OUI); holds 2 IEEE prefixes (00:12:56, 00:19:A1) [Confirmed] — IEEE OUI Registry, cross-corroborated by Wireshark the Wireshark manufacturer database and maclookup.app

HQ / country

00:19:A1 → 60-39 Kasan-dong, Kumchon-ku, Seoul, South Korea 153-023; 00:12:56 → 459-9 Kasan-dong, Kumchon-gu, Seoul, South Korea 153-023 [Confirmed] — IEEE MA-L

Company status

defunct as an independent entity — merged into LG Electronics on 2000-09-01; no current standalone registrations found [Likely] — Namu Wiki (ko)

Device types

PBX/electronic switching systems, network transmission and satellite comms gear, CDMA mobile network systems, Freeway/Cyon-branded mobile handsets [Likely] — Namu Wiki corporate history (secondary source)

Notable products

Freeway-branded and Cyon-branded mobile handsets (pre-2000 CDMA era) [Likely] — Namu Wiki (ko)

Verified sample prefixes (both MA-L, LG INFORMATION & COMM.)

00:12:56, 00:19:A1 [Confirmed] — IEEE MA-L / Wireshark the Wireshark manufacturer database / maclookup.app (three-way agreement)

Special note

maclookup.app displays per-prefix "Registration Date" values of 2004-09-09 (00:12:56) and 2006-09-25 (00:19:A1) — these are third-party database artifacts, not IEEE facts; IEEE's public OUI data publishes no assignment/registration dates. Both dates postdate the 2000-09-01 LG Electronics merger by 4-6 years, underscoring that they are scrape/tracking timestamps rather than true assignment dates.

[Confirmed] — maclookup.app cross-checked against IEEE MA-L

Related vendors

LG Electronics (Mobile Communications) — successor entity registered under a separate OUI at the same Kasan-dong/Gasan-dong, Kumchon-gu/Geumcheon-gu, Seoul site [Likely] — IEEE OUI Registry cross-reference

Analyst note

A device presenting a 00:12:56 or 00:19:A1 OUI in 2026 is almost certainly either surviving legacy enterprise telephony/PBX hardware or a stale vendor-string artifact — the registrant stopped existing independently in 2000, and IEEE OUI assignee strings are known to go stale for decades after a merger without being updated.
