MAC address vendor

ITTIM Technology Co., Ltd. — 5 prefixes (MA-L)

Primary prefix
38:39:04
Block
MA-L
Status
Active

Summary

// what this is
ITTIM Technology is registered to MAC prefix 38:39:04 and 4 more in the IEEE OUI database. When a device's MAC address begins with 38:39:04, that block was registered by ITTIM Technology — the OUI identifies the maker of the network hardware, which is not always the brand on the device.
// analyst note
Multi-block MA-L registration plus independent FCC corroboration distinguishes this from a single-OUI shell; downstream host-device models and detailed company history remain unverified.

About this vendor.

Updated  ·  Confidence: Medium

A MAC address beginning with 38:39:04, 68:39:43, CC:E5:36, 5C:C3:36, or 48:0E:13 belongs to ITTIM Technology Co., Ltd., a Beijing-based Wi-Fi module manufacturer, and typically identifies an embedded 2.4GHz WiFi radio module built into a router, gateway, or other IoT/consumer-electronics host device rather than a standalone product.

Five separate IEEE MA-L blocks share the identical organization name "ittim" and the identical registered address in Haidian District, Beijing. That repetition across five distinct /24 allocations is itself a signal of an active registrant rather than a one-off filing, since IEEE issues each block on a separate request.

A related but textually distinct registry entry, B0:41:1D, is assigned to "ITTIM Technologies" at a different building on the same Beijing street. The registry treats the two organization-name strings as separate entities, so that prefix is tracked apart from this entry rather than folded in.

Independent regulatory filings corroborate the company outside the MAC-lookup ecosystem: two FCC ID grants (2AEU8SD06, 2AEU8UB12) for "2.4GHz WiFi Module" hardware were filed by "Ittim Technology Co.,Ltd." from a Shanghai address, naming a responsible contact. Both classify the product as an OEM/modular radio component for integration into other devices.

The company also maintains a corporate site at ittim.cn, though its TLS certificate is currently expired, so page content could not be independently verified live in this pass; treat unattributed background claims about the company's founding as Likely rather than Confirmed. No CVEs or security advisories naming ITTIM were found.

IEEE assignment
5 prefixes → "ittim" (exact org string), registered Beijing, CN [Confirmed] — the IEEE MA-L registry, IEEE MA-L
Registry / block size
MA-L (24-bit OUI) x5 [Confirmed] — the IEEE MA-L registry. NOTE: IEEE's public OUI data publishes no assignment/registration date; no date is recorded for any of these five prefixes.
HQ / country
1202, No.6, Zhongguancun South Street, Haidian District, Beijing 100080, CN [Confirmed] — IEEE MA-L registry
Company status
active — corroborated by two FCC filings (2015, 2017) and a live (if unverifiable-over-HTTPS) corporate domain [Confirmed for filings; Likely for current operating status] — fccid.io, ittim.cn
Device types
2.4GHz WiFi radio modules (OEM/ODM component) [Confirmed] — fccid.io/2AEU8SD06, fccid.io/2AEU8UB12
Notable products
no specific downstream host-device models (routers, cameras, etc.) identified in this pass [Unknown]
Verified sample prefixes
38:39:04, 68:39:43, CC:E5:36, 5C:C3:36, 48:0E:13 (all MA-L, org "ittim") [Confirmed] — the IEEE MA-L registry
Related entry (not merged)
B0:41:1D → "ITTIM Technologies", different address on the same street [Confirmed] — the IEEE MA-L registry
Historic block / registration date
Unknown — IEEE publishes no registration/allocation date for OUI/MA-L assignments; a third-party aggregator (maclookup.app) displays a date for the separate B0:41:1D entry and frames it as "the IEEE registration date," but that framing is the aggregator's own and is not an IEEE fact — not recorded here. [Confirmed that no IEEE date exists]
Security note
no CVEs or security advisories naming ITTIM Technology / ITTIM Technologies were found in this pass [Unknown — absence of evidence, light pass only]
Related vendors
"ITTIM Technologies" (B0:41:1D), a textually distinct registry entry at a nearby Beijing address; relationship to this entity is unconfirmed
Analyst note
five same-name, same-address MA-L blocks plus two independent FCC filings place this well above a bare single-OUI shell — treat as a genuine, identifiable OEM Wi-Fi module manufacturer, not a thin registration.
