MAC address vendor

Advantage Electronics, Inc. — single OUI (54:1F:D5, MA-L)

Primary prefix
54:1F:D5
Block
MA-L
Status
Active

Summary

// what this is
Advantage Electronics is registered to MAC prefix 54:1F:D5 in the IEEE OUI database. When a device's MAC address begins with 54:1F:D5, that block was registered by Advantage Electronics — the OUI identifies the maker of the network hardware, which is not always the brand on the device.
// analyst note
This OUI resolves to a single, identifiable, operating company rather than a bare shell registration, but only one MA-L block is held and no device/product was publicly confirmed against this prefix — treat a match as Advantage Electronics-manufactured hardware of unconfirmed device type.

About this vendor.

Updated  ·  Confidence: Likely  ·  8 sources  ·  How this page is checked

A MAC address starting with 54:1F:D5 is registered to Advantage Electronics, Inc., a single IEEE MA-L block held by a real, operating contract electronics manufacturer in Greenwood, Indiana. No specific product, model, or device type could be tied to this prefix from public sources, so identification stops at the company level rather than a device class.

Advantage Electronics, Inc. is a contract EMS (electronics manufacturing services) provider in business since 1984, offering circuit assembly, industrial control systems, custom microprocessor-based designs, test-system development, and cable/harness assembly to industrial clients in plastics, chemical, automotive, and telecommunications sectors. As a contract manufacturer, this OUI plausibly appears on a variety of client-designed embedded boards rather than one identifiable consumer product line.

The company holds exactly one IEEE OUI assignment under this name — no second MA-L, MA-M, or MA-S block was found in the local registries. Independent business directories place the company at a street address consistent with the PO Box recorded in the IEEE registry, corroborating that the registrant is a genuine, still-operating entity rather than a shell registration created only to hold a MAC block.

Search results also surface an unrelated, similarly named electronics distributor that should not be confused with this Greenwood, Indiana registrant. No CVE, security advisory, or malware association was found tied to this OUI or vendor name as of an August 2026 search.
