Nanjing Jiahao Technology Co., Ltd. — 7 prefixes (MA-L)
Summary
- // what this is
- Nanjing Jiahao Technology is registered to MAC prefix
F0:2B:18and 6 more in the IEEE OUI database. When a device's MAC address begins withF0:2B: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.
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.
- Organization name

- 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
