The slug "vendor-shenzhen-jingxun" resolves to two distinct but closely related legal entities in the IEEE MA-L registry, both filed to the same physical address at 3/F, A5 Building, Zhiyuan Community, No. 1001 Xueyuan Road, Nanshan District, Shenzhen, Guangdong, China. The first, "Shenzhen Jingxun Software Telecommunication Technology Co., Ltd." (postcode 518055), holds ten MA-L blocks; the second, "Shenzhen Jingxun Technology Co., Ltd." (postcode 518071), holds six. The shorter "Jingxun Technology" name appears to be a successor or renamed entity, and consolidating both under one vendor page is more useful than minting sixteen near-identical per-prefix pages that all trace to the same Nanshan address. All sixteen assignments are MA-L (24-bit OUI, ~16.7 million addresses each), for a combined pool on the order of 268 million MAC addresses — a footprint consistent with a volume manufacturer of networking or IoT hardware, though no public product catalog, FCC/CE filing, or device-type classification was retrievable to confirm what the company actually ships. The company name's "Software Telecommunication" suggests a telecom/networking or CPE focus, but that is inferred from the name alone. No CVEs, NVD/CPE entries, or documented security advisories reference "Jingxun" as of June 2026; the absence reflects limited security-research attention rather than a verified clean record. The practical caveat for any Jingxun OUI work: a globally-administered Jingxun prefix reliably identifies hardware registered to one of these two entities, but the lack of a confirmed device type means OUI alone does not tell you what kind of device you are looking at.
- IEEE assignment
- 16 MA-L prefixes across two entities — (1) Shenzhen Jingxun Software Telecommunication Technology Co., Ltd. (10 blocks), (2) Shenzhen Jingxun Technology Co., Ltd. (6 blocks) [Confirmed] — IEEE MA-L (oui.csv cache), corroborated by maclookup.app
- Registry / block size
- all MA-L (24-bit OUI); no MA-M or MA-S blocks found [Confirmed] — IEEE registries (oui.csv hits; mam.csv and oui36.csv returned no hits)
- Entity 1 prefixes (Jingxun Software Telecommunication Technology)
- 2C:FD:B4, 88:50:F6, E8:D0:3C, 5C:FB:7C, 04:CB:88, D8:37:3B, B8:F6:53, 30:C0:1B, 28:FA:19, F4:BC:DA [Confirmed] — IEEE MA-L / maclookup.app
- Entity 2 prefixes (Jingxun Technology)
- 4C:3C:8F, 20:18:5B, E8:26:CF, 10:28:74, 40:C1:F6, 18:90:67 [Confirmed] — IEEE MA-L / maclookup.app
- HQ / country
- 3/F, A5 Building, Zhiyuan Community, No. 1001 Xueyuan Road, Nanshan District, Shenzhen, Guangdong, CN (Entity 1 postcode 518055; Entity 2 postcode 518071) [Confirmed] — IEEE MA-L
- Registration date
- Unknown — IEEE publishes NO assignment/registration date for MA-L blocks (oui.csv columns are only Registry, Assignment, Organization Name, Organization Address). Third-party "date registered" values on maclookup.app (e.g. 2017-04-18 for Entity 1's first block, 2022-06-21 for Entity 2's first block) are database artifacts, NOT IEEE facts. [Unknown] — IEEE oui.csv schema
- Device types
- Unknown — no public product catalog, FCC/CE filing, or device-type data retrievable. Name implies telecom/networking/CPE focus, inferred only. [Unknown] — open-source search (no corroboration found)
- Company website
- Unknown — jingxun.net appears associated but returned a TLS certificate mismatch (ERR_TLS_CERT_ALTNAME_INVALID); no working vendor URL confirmed. [Unknown]
- Security context
- No CVEs, NVD/CPE entries, or Exploit-DB records found for "Jingxun" as of June 2026; absence reflects low research attention, not a verified-clean state. Two-entity allocation may indicate OEM/white-label manufacturing, which can complicate supply-chain provenance — unconfirmed. [Confirmed absence of records] — nvd.nist.gov, cve.org
- Analyst note
- A Jingxun OUI on a globally-administered address identifies hardware registered to one of the two Shenzhen Jingxun entities; the unconfirmed device type means OUI alone does not classify the device. Treat the two names as one vendor at one address.
