Observint Technologies, Inc. MAC Prefixes: Vendor Identified, Device Unknown
Summary
- // what this is
- Observint Technologies is registered to MAC prefix
50:DC:D0and 1 more in the IEEE OUI database. When a device's MAC address begins with50:DC:D0, that block was registered by Observint Technologies — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- The supplied projection shows two 24-bit MA-L prefixes. For both first octets (0x50 and 0x64), Group bit (mask 0x01) and Local bit (mask 0x02) are zero. These bits are fixed for an exact literal prefix match; setting either changes the prefix. Each prefix allows 2^24 (16,777,216) suffix values, which is not a device or shipment count. A match establishes registry assignment only, not the identity of a device or use of a company product.
About this vendor.
A MAC address beginning with 50:DC:D0 or 64:25:5E matches an IEEE MA-L assignment to Observint Technologies, Inc.; the supplied records do not identify a device category or product for either prefix.
Both assignments are 24-bit prefixes, leaving 24 bits for address suffixes. For each prefix, that yields 16,777,216 possible suffix values, a mathematical range rather than a count of devices, shipments, or addresses actually in use.
The first octets, 50 and 64, each have Group and Local bits set to zero. As RFC 7042 explains, these bits are respectively bit masks 01 and 02 in the first octet. Those values are fixed for an exact prefix match; switching either bit changes the prefix and no longer matches the literal assignment. A match identifies registry allocation only, not a specific device, product, current vendor identity, or security state. IEEE CSV assignment dates are unavailable.
