MAC address vendor

AFE Inc. MAC Prefix EC:57:0D — Device Unknown

Primary prefix
EC:57:0D
Block
MA-L

Summary

// what this is
AFE is registered to MAC prefix EC:57:0D in the IEEE OUI database. When a device's MAC address begins with EC:57:0D, that block was registered by AFE — the OUI identifies the maker of the network hardware, which is not always the brand on the device.
// analyst note
A prefix match identifies a registry assignment, not a specific device, product, deployment, or security state.

About this vendor.

Updated  ·  Confidence: High  ·  2 sources  ·  How this page is checked

A MAC address beginning EC:57:0D is registered to AFE Inc.; the supplied evidence does not identify a device type or product that uses it. The IEEE MA-L record lists one assignment for the company, and gives no assignment date.

This is a 24-bit prefix in a 48-bit MAC address, leaving 24 bits after the match. A matching address shares the registered prefix, but that alone does not identify a particular device, deployment, or product. The remaining bits allow 16,777,216 possible suffix values; this is a mathematical range, not a device or shipment count.

The first octet, EC (binary 11101100), has Group bit 0 and Local bit 0. In this exact prefix those bits are fixed: changing either creates a different prefix. RFC 7042 explains that these bits distinguish group and local address semantics. A captured match therefore establishes a prefix match to the registry assignment, not the address's observed use or safety.
