TKH Security B.V. MAC prefixes: vendor identified, device unknown
Summary
- // what this is
- TKH Security is registered to MAC prefix
00:04:7Eand 1 more in the IEEE OUI database. When a device's MAC address begins with00:04:7E, that block was registered by TKH Security — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- A matching prefix establishes a registry-prefix match only; no supplied evidence maps either prefix to a product or device category.
About this vendor.
A MAC address beginning 00:04:7E or 00:1E:D1 matches an IEEE MA-L assignment to TKH Security B.V.; the assignment does not identify a specific device. The available company page names TKH Security B.V. and describes an IPROTECT Access Control solution used in a customer story, but does not map that product or any device category to either prefix.
Both assignments are 24-bit prefixes, leaving 24 bits for suffix values: 16,777,216 possible values per prefix. In each prefix, the first octet is 00, so the Group bit and Local bit are both zero. Those bits are fixed for an exact literal match; changing either bit produces a different prefix. The suffix-value count is a mathematical address space size, not a count of devices, deployments, or shipments.
A captured matching address supports a registry-prefix match only. It cannot by itself establish which product or device sent it, whether it was deployed, or its current operator or security state. Assignment dates are unavailable in these IEEE CSV records.
