Titan Electronics, Inc. — registry identity unresolved
Summary
- // what this is
- Titan Electronics is registered to MAC prefix
00:04:D9and 1 more in the IEEE OUI database. When a device's MAC address begins with00:04:D9, that block was registered by Titan Electronics — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- The assignment rows contain different organization-name strings; the evidence does not establish a common legal entity. Each 24-bit prefix leaves 24 suffix bits, or 16,777,216 possible suffix values. Both first-octet Group and Local bits are zero for these exact prefixes; bit changes produce different prefixes. Address interpretation follows RFC 7042, section 2.1.
About this vendor.
A MAC address beginning with 00:04:D9 or 00:20:81 matches an IEEE MA-L registry assignment, but the records do not establish which device or vendor the address identifies. The organization-name strings differ, and the supplied evidence does not show that they represent the same legal entity.
Both assignments are 24-bit prefixes of 48-bit MAC identifiers, leaving 24 suffix bits and 16,777,216 possible suffix values for each. That is a mathematical address space, not a device or shipment count. The records include a Taiwan country indication for 00:04:D9 and a US indication for 00:20:81; they provide no verified products, industry, or device categories linked to either prefix.
For both exact prefixes, the first-octet Group and Local bits are zero. A captured address that matches the exact prefix therefore has those bits set to zero. Changing either bit changes the prefix and is not a variation within that fixed assignment. An exact prefix match supports registry-assignment identification only; it does not identify a particular device, product, current vendor identity, or security state.
