ADTEC PRODUCTIONS, INC. — device identity unknown for 00:90:1F
Summary
- // what this is
- Adtec Productions is registered to MAC prefix
00:90:1Fin the IEEE OUI database. When a device's MAC address begins with00:90:1F, that block was registered by Adtec Productions — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- The exact prefix fixes the Group and Local bits in its first byte at zero. A match identifies the registry assignment only; the 24-bit suffix space contains 16,777,216 possible values, not a device or shipment count.
About this vendor.
A MAC address beginning 00:90:1F matches an IEEE MA-L assignment to ADTEC PRODUCTIONS, INC.; the assigned prefix does not identify a specific device or device type. The IEEE record lists the company name and an address in Nashville, Tennessee, United States, but provides no device or product mapping.
This is a 24-bit prefix, so matching requires the first three octets to equal 00:90:1F. The remaining 24 bits allow 16,777,216 possible suffix values; that is a mathematical address-space count, not a count of devices or shipments. For this exact prefix, the first-byte Group and Local bits are both zero. Changing either bit produces a different prefix.
RFC 7042 describes 48-bit MAC identifiers as a prefix followed by additional bits and discusses the Group and Local bits. A matching address supports identification of the registry assignment only; it does not establish a particular product, current vendor identity, deployment, or security state.
