Advanced Technical Support, Inc. — MAC Prefix Identification
Summary
- // what this is
- Advanced Technical Support is registered to MAC prefix
A0:07:B6in the IEEE OUI database. When a device's MAC address begins withA0:07:B6, that block was registered by Advanced Technical Support — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- A prefix match supports registry attribution and interpretation of the fixed /24 boundary; it does not identify a specific device, product, operating system, current vendor identity, or security state. The /24 leaves 24 suffix bits, or 16,777,216 possible values, not an observed device count. For A0:07:B6, the first-byte Group and Local bits are both 0; changing either bit changes the prefix.
About this vendor.
A MAC address beginning A0:07:B6 matches an IEEE MA-L assignment registered to Advanced Technical Support, Inc. The record identifies the registrant; it does not establish the device category, product, deployment, or current identity of the device using an address. No retrieved source maps this exact prefix to a device type or product.
This is a 24-bit prefix, so a matching 48-bit address has 24 remaining bits. Those bits allow 16,777,216 possible suffix values; that is a mathematical range, not a count of devices or shipments. The first byte, A0, has Group and Local bits both clear. Under RFC 7042, those bits indicate group versus individual and globally versus locally administered address semantics. For this exact prefix, they are fixed; changing either bit changes the prefix and is not variation within this assignment.
The IEEE record lists the country as US. The supplied IEEE CSV record does not include an assignment date. A prefix match can support registry attribution and bit-boundary interpretation, but cannot by itself identify a particular device, product, operating system, current vendor identity, or security state.
