NTX Electronics YangZhou co.,LTD — two MA-L assignments
Summary
- // what this is
- NTX Electronics YangZhou is registered to MAC prefix
A4:3C:D7and 1 more in the IEEE OUI database. When a device's MAC address begins withA4:3C:D7, that block was registered by NTX Electronics YangZhou — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- Each prefix is 24 bits, with 24 suffix bits and 16,777,216 possible suffix values. For both exact prefixes the first-byte Group and Local bits are zero. A matching first 24 bits indicates a registry assignment only, not a particular device, product, operator status, or security condition.
About this vendor.
A MAC address beginning with A4:3C:D7 or AC:04:E6 matches an MA-L assignment registered to NTX Electronics YangZhou co.,LTD. The records identify the assignee; they do not establish which device or product uses a matching address, or whether it is currently deployed.
Both prefixes are 24 bits long, leaving 24 bits for suffix values: 16,777,216 possible values per prefix. This is a mathematical address-space size, not a count of devices or shipments. RFC 7042 explains that the first octet carries Group and Local bits. For these exact prefixes both bits are zero. Turning either bit on changes the prefix, so addresses with those altered bits are not exact matches to these assignments.
For identification, compare the first three octets of the captured 48-bit MAC address against each full prefix. A match supports the registry-assignment identification only; it does not identify a particular model, operating system, current vendor status, or security condition.
- Device category
- Unknown — no evidence maps a device category to these exact prefixes.
- Address match
- Compare the first 24 bits of the MAC address with either prefix; the remaining 24 bits are suffix space, not a device count [Confirmed] — https://www.rfc-editor.org/rfc/rfc7042.txt
