MAC address vendor

Nanjing Jiahao Technology Co., Ltd. — 7 prefixes (MA-L)

Primary prefix
F0:2B:18
Block
MA-L

Summary

// what this is
Nanjing Jiahao Technology is registered to MAC prefix F0:2B:18 and 6 more in the IEEE OUI database. When a device's MAC address begins with F0:2B:18, that block was registered by Nanjing Jiahao Technology — the OUI identifies the maker of the network hardware, which is not always the brand on the device.
// analyst note
Treat matches to this vendor as identifying a real IEEE-registered assignee across 7 blocks; do not infer device category (router/IoT/camera) without corroborating evidence — none currently exists.

About this vendor.

Updated  ·  Confidence: Medium

Nanjing Jiahao Technology Co., Ltd. holds seven distinct MA-L (24-bit OUI) blocks in IEEE's registry, all recorded under one consistent legal name and one registered address in the Moling Industrial Park, Jiangning district of Nanjing, Jiangsu, China. Seven separate assignments to a single, unvarying registrant is itself a meaningful substance signal — a bare shell or one-off registrant does not typically accumulate seven blocks over time — but that substance stops at the registry data. No company website, no Alibaba/1688 storefront, no FCC ID filing, no device teardown record, and no security or CVE reporting under this exact name could be located, so the vendor's actual product line and device category remain unverified from public sources. The org holds MA-L blocks only; no MA-M or MA-S (smaller-block) assignments were found under the same name. Any per-prefix page rendered from this entry should present the multi-block registration as the confirmed fact and leave device type as Unknown rather than guessing at a router, camera, or IoT category.

Registry / block type
MA-L (24-bit OUI) only — no MA-M/MA-S blocks found under this org name [Confirmed] — the IEEE MA-M registry, the IEEE MA-S registry (no matches)
Registered address
Moling Industrial Park, Development Zone, Jiangning, Nanjing, Nanjing, Jiangsu, CN 211111 [Confirmed] — the IEEE MA-L registry
Prefix count
7 assignments — F0:2B:18, 4C:4D:66, 14:BE:FC, 90:27:59, 8C:1E:CB, 70:FD:88, 90:C3:5F [Confirmed] — the IEEE MA-L registry; cross-checked against the Wireshark manufacturer database (7 of 7 prefixes confirmed matching)
Third-party prefix-count corroboration
maclookup.app independently lists 7 prefixes for this vendor (one earlier crawl snapshot showed 6, likely a stale partial index) [Likely] — https://maclookup.app/vendors/nanjing-jiahao-technology-co-ltd
Assignment/registration date
Unknown — IEEE's OUI registry publishes no per-assignment date; maclookup.app's displayed "registered/updated" dates are that tool's own crawl/database metadata, not an IEEE-published fact, and are not recorded as an IEEE date [Unknown] — the IEEE MA-L registry (no date column); https://maclookup.app/vendors/nanjing-jiahao-technology-co-ltd (third-party artifact, not adopted)
Company operating status / website
Unknown — no company website, B2B storefront, FCC ID filing, device teardown, or news/patent record found under this exact name [Unknown] — WebSearch (English + Chinese "南京佳浩" queries), fcc.report-style queries, device.report — all returned no relevant hits
Device type / product corroboration
Unknown — no product, teardown, or marketing material ties any of the 7 OUIs to a specific device category [Unknown] — no source located
Security context
Unknown/none found — no CVE, botnet, or firmware-vulnerability reporting names this vendor or its prefixes [Unknown] — WebSearch (CVE/botnet/firmware queries), no hits
IANA reference
not applicable to an OUI/MA-L entry; left blank rather than fabricated [Confirmed by omission] — n/a
