MAC address vendor

NXP (China) Management Ltd. — 2 prefixes (MA-L)

Primary prefix
54:27:8D
Block
MA-L
Status
Active

Summary

// what this is
NXP is registered to MAC prefix 54:27:8D and 1 more in the IEEE OUI database. When a device's MAC address begins with 54:27:8D, that block was registered by NXP — the OUI identifies the maker of the network hardware, which is not always the brand on the device.
// analyst note
Both OUI blocks are dedicated MA-L registrations to this single legal entity, not sub-allocations of a shared IEEE base. The entity functions as NXP's country-level administrative headquarters for China rather than a manufacturing site, so equipment observed with these prefixes should be attributed to whichever NXP business unit actually deployed it, not assumed to be a specific product line.

About this vendor.

Updated  ·  Confidence: Medium  ·  11 sources  ·  How this page is checked

A MAC address beginning with 54:27:8D or B8:7C:6F is registered to NXP (China) Management Ltd., the Shanghai-based entity that serves as NXP Semiconductors' regional administrative headquarters for China. Because this is a holding/management company rather than a manufacturing or design site, no specific device or product line is publicly attributable to either block.

NXP announced the establishment of this entity on 2015-03-26 by converting an existing NXP China company, expanding its mandate to cover all of NXP's China operations — investment, strategy, capital operations, and financial management — rather than a single business line. The announcement named then-CEO Rick Clemmer and NXP China CEO Li Zheng.

The IEEE registry lists two MA-L (/24) blocks under this exact legal name, both recorded at the same Shanghai address, with no MA-M or MA-S assignments found. Independent third-party lookups (udger.com, maclookup.app) and the project's bundled Wireshark manufacturer database each list the identical pair of prefixes, corroborating the registry entry.

This differs from NXP's Tianjin and Taiwan sibling entries, which are back-end IC packaging and test sites — that framing does not transfer here. No CVE or security advisory ties to this entity or its prefixes as of an August 2026 search, and third-party "registered" dates for these blocks are scrape artifacts, not IEEE facts.

Third-party date artifact
maclookup.app shows scraped "registered" dates (2018-06-13 for 54:27:8D, 2018-04-05 for B8:7C:6F) — these are database-scrape artifacts of that third party's own copy, not IEEE facts [Confirmed as a negative finding] — maclookup.app

Analyst note
Both blocks are dedicated MA-L registrations to this single legal entity, not sub-allocations of a shared IEEE base; the entity is an administrative/holding headquarters, not a design or manufacturing site, so equipment carrying these addresses should be attributed to whichever NXP business unit built it, not assumed to be a specific product line.
