ACK Networks,Inc. — device type Unknown
Summary
- // what this is
- ACK Networks is registered to MAC prefix
C4:0E:45in the IEEE OUI database. When a device's MAC address begins withC4:0E:45, that block was registered by ACK Networks — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- A matching MAC prefix identifies the registry assignment, not a particular device, deployment, current vendor identity, or security state.
About this vendor.
A MAC address beginning C4:0E:45 matches the IEEE MA-L assignment to ACK Networks,Inc.; the supplied records do not identify a device category or product using this prefix. A match identifies the registered prefix, not a particular device, deployment, or current vendor identity.
This is one 24-bit prefix, leaving 24 bits for suffix values: 16,777,216 possible values. That is a mathematical range, not a count of devices or shipments. The first octet C4 has Group bit 0 and Local bit 0. For this exact prefix, those bits are fixed; changing either changes the prefix and no longer matches this assignment.
RFC 7042 describes 48-bit MAC identifiers as an assigned initial prefix followed by additional bits, and explains the Group and Local bits. The supplied IEEE row gives the registrant name but no assignment date. It does not establish products, industry, or device types for this prefix.
- Identification
C4:0E:45is assigned to ACK Networks,Inc.; device category Unknown. [Confirmed] — https://standards-oui.ieee.org/oui/oui.csv- Registry
- MA-L; one assigned 24-bit prefix. [Confirmed] — https://standards-oui.ieee.org/oui/oui.csv
- Matching boundary
- Match the first 24 bits (
C4:0E:45); the remaining 24 bits allow 16,777,216 possible suffix values, not an observed device count. [Confirmed] — https://www.rfc-editor.org/rfc/rfc7042.txt - Address bits
- Group bit 0 and Local bit 0 are fixed for this exact prefix; flipping either changes the prefix. [Confirmed] — https://www.rfc-editor.org/rfc/rfc7042.txt
