Air Products and Chemicals, Inc. MAC Prefix: Vendor Recorded, Device Unknown
Summary
- // what this is
- Air Products and Chemicals is registered to MAC prefix
00:07:5Ain the IEEE OUI database. When a device's MAC address begins with00:07:5A, that block was registered by Air Products and Chemicals — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- The exact 24-bit prefix fixes the first-octet Group bit and Local bit at zero. The remaining 24 bits permit 16,777,216 suffix values; this theoretical capacity is not an observed device or shipment count. A prefix match indicates a registry assignment, not a particular device or current deployment.
About this vendor.
A MAC address beginning 00:07:5A is registered to Air Products and Chemicals, Inc.; the assignment does not identify a specific device type. The IEEE record lists one MA-L assignment for this legal entity. A registry match establishes the recorded assignment, not which company or device is currently using a captured address.

00:07:5A is a 24-bit prefix, leaving 24 bits in a 48-bit address. That creates 16,777,216 possible suffix values within the prefix; it is a mathematical address-space count, not a count of devices, shipments, or addresses observed in use. The first octet is 00: its Group and Local bits are both zero, so those bits are fixed for this exact prefix. Changing either bit produces a different prefix.

The IEEE record gives the organization name and a US address, supporting country-level identification as the United States. The supplied evidence does not establish company products, industry, website, or device categories associated with this assignment. [https://standards-oui.ieee.org/oui/oui.csv]
