leerang corporation holds a single MA-L block, 68:2C:4F, registered in the IEEE OUI database with a Seoul, South Korea address (#101, 69, Jongam-ro 28-gil, Seongbuk-gu, Seoul, KR 02797). That registry row is the only firm fact about this vendor: the prefix, the organization name, the MA-L class, and the Korean address all reconcile cleanly across the IEEE source and two independent third-party lookups (maclookup.app, hwaddress.com). Beyond the registration itself the public footprint is essentially empty. There is no discoverable vendor website, no published product line, and no sightings of devices bearing this OUI in network scans, community forums, packet captures, or retail listings as of June 2026. The name pattern is consistent with a Korean-origin company (Korean: 이랑), but that is conjecture, not a sourced claim — the registry address is the authoritative country signal, and it reads KR. No CVEs, advisories, or threat-intelligence references exist for the vendor name or the 68:2C:4F prefix; that absence reflects a negligible public footprint, not a clearance. A note on dating: IEEE publishes no registration dates, so the only firm fact is that the block exists. The "first seen" value of 2023-03-09 shown by maclookup.app is a third-party database indexing artifact, not an IEEE-issued registration date, and is not treated as one here. The honest output for device type, website, and usage context is a sourced null.
- IEEE assignment
- 68:2C:4F → leerang corporation [Confirmed] — IEEE MA-L (oui.csv), corroborated by maclookup.app and hwaddress.com
- Registry / block size
- MA-L (24-bit OUI); single prefix covering 68:2C:4F:00:00:00–68:2C:4F:FF:FF:FF (~16.7M addresses) [Confirmed] — IEEE MA-L; not present in MA-M (mam.csv) or MA-S (oui36.csv) registries. NOTE: IEEE's public OUI data publishes NO assignment/registration date (oui.csv columns are only Registry, Assignment, Organization Name, Organization Address); any "date registered" on third-party tools is a database artifact, not an IEEE fact.
- HQ / country
- #101, 69, Jongam-ro 28-gil, Seongbuk-gu, Seoul, KR 02797 — country KR (South Korea) [Confirmed] — IEEE MA-L (registry address). The maclookup.app/hwaddress.com listings surface the name and prefix but did not independently re-publish the full street address; the registry CSV is the authority for it.
- Company status
- Unknown — no vendor website or corporate registry record located to confirm active/dissolved status [Unknown]
- Device types
- Unknown — no device type, product line, or product sightings found in any public source (no forum posts, packet captures, scan discussions, or retail listings reference the 68:2C:4F OUI) [Unknown]
- Notable products
- Unknown — none discoverable [Unknown]
- Verified sample prefix (MA-L, leerang corporation)
- 68:2C:4F [Confirmed] — IEEE MA-L / maclookup.app / hwaddress.com
- Registration date
- Unknown as an IEEE fact — IEEE publishes none. maclookup.app shows a "first seen" of 2023-03-09, explicitly a third-party indexing artifact and not an IEEE registration date [Likely artifact, single-source] — maclookup.app
- Security context
- No CVEs, advisories, or threat-intel references found for "leerang corporation" or OUI 68:2C:4F; no known exploit, botnet, or malware association. Absence of findings is not a security clearance — it reflects only the vendor's negligible public footprint. [Confirmed absence as of search date]
- Related vendors
- None identified. Not to be confused with unrelated similarly-named companies (Leer Electronics, Fuan Leercon Electronic, LEEDARSON). [Likely] — web search disambiguation
- Analyst note
- A 68:2C:4F address on a globally-administered MAC reliably identifies hardware from this registrant, but with no published product line the OUI gives the device's vendor of record and little else; treat asset-classification value as limited until a product association surfaces.
