MAC address vendor

QNAP Systems, Inc. MAC Prefixes: Vendor Identified, Device Unknown

Primary prefix
24:5E:BE
Block
MA-L

Summary

// what this is
QNAP Systems is registered to MAC prefix 24:5E:BE and 1 more in the IEEE OUI database. When a device's MAC address begins with 24:5E:BE, that block was registered by QNAP Systems — the OUI identifies the maker of the network hardware, which is not always the brand on the device.
// analyst note
Both assignments are 24-bit prefixes with Group bit 0 and Local bit 0. An exact match identifies the listed registry assignment, not a particular device or deployment.

About this vendor.

Updated  ·  Confidence: Medium  ·  2 sources  ·  How this page is checked

A MAC address beginning with 24:5E:BE or E8:43:B6 is assigned in IEEE records to QNAP Systems, Inc.; the assignment does not identify a specific device. Both are MA-L assignments with 24-bit matching boundaries, leaving 24 bits, or 16,777,216 possible suffix values, under each prefix. That is a count of possible suffix values, not a count of devices or shipments.

For both prefixes, the first octet has Group bit 0 and Local bit 0. Under RFC 7042’s bit interpretation, those bits are fixed for an exact literal prefix match. Changing either bit produces a different prefix; this does not imply variation within the assigned prefix. A matching captured address supports the registry assignment only. It does not establish a particular product, operating system, current vendor identity, deployment, traffic prevalence, or security state.

IEEE CSV records list QNAP Systems, Inc. under MA-L assignments 245EBE (24:5E:BE) and E843B6 (E8:43:B6). The registrant address includes country code TW. Assignment dates: Unknown. Product, industry, and website: Unknown.
