MAC address vendor

AFT Atlas Fahrzeugtechnik GmbH — 00:23:FD (MA-L)

Primary prefix
00:23:FD
Block
MA-L

Summary

// what this is
AFT Atlas Fahrzeugtechnik is registered to MAC prefix 00:23:FD in the IEEE OUI database. When a device's MAC address begins with 00:23:FD, that block was registered by AFT Atlas Fahrzeugtechnik — the OUI identifies the maker of the network hardware, which is not always the brand on the device.
// analyst note
Single-OUI registration by a real, identifiable automotive engineering company; no device-level corroboration exists, so a match on 00:23:FD identifies the registrant, not a confirmed product or device class.

About this vendor.

Updated  ·  Confidence: Medium  ·  5 sources  ·  How this page is checked

A MAC address starting with 00:23:FD belongs to AFT Atlas Fahrzeugtechnik GmbH, a German automotive engineering firm — no source identifies a specific device or product line carrying this prefix, so the match confirms the registrant company, not a piece of hardware.

AFT Atlas Fahrzeugtechnik GmbH was a real, substantive company: a wholly-owned subsidiary of Schaeffler AG founded in 1979, employing roughly 100-199 people out of Werdohl, Germany, and working in mechatronic systems, transmission and drivetrain technology, ECU calibration, and vehicle integration services. Effective March 1, 2013, the company was renamed Schaeffler Engineering GmbH as part of a corporate repositioning; the IEEE registry record still carries the pre-rename legal name.

Only one OUI (00:23:FD, MA-L) is on file under either the "AFT Atlas Fahrzeugtechnik" name or the successor "Schaeffler Engineering" name. No Wireshark community sighting, security scan report, or product manual was found tying any specific hardware to this prefix, and no CVE, malware association, or security advisory naming this company or the prefix was found as of an August 2026 search.

Given the company's line of business, in-house test-bench, prototype-ECU, or lab networking equipment is a plausible use of the block, but this is inference from the registrant's business, not a confirmed device-type finding.
