ADVALY SYSTEM Inc. MAC prefix: vendor identification only
Summary
- // what this is
- Advaly System is registered to MAC prefix
30:5D:A6in the IEEE OUI database. When a device's MAC address begins with30:5D:A6, that block was registered by Advaly System — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- A MAC beginning 30:5D:A6 matches the first 24 bits of the listed assignment. The first octet's Group and Local bits are both zero for this exact prefix; changing either bit changes the prefix. The 24 remaining bits allow 16,777,216 suffix values, not an inferred number of devices or shipments. A match identifies the registry assignment only.
About this vendor.
A MAC address beginning 30:5D:A6 matches an IEEE MA-L assignment to ADVALY SYSTEM Inc.; the record does not identify a device type or specific product. A prefix match establishes the registered assignment, not who operates a device today or whether it is safe.
The assignment covers the first 24 bits of a 48-bit MAC address. That leaves 24 suffix bits, or 16,777,216 possible suffix values. This is a mathematical address-space count, not a count of devices, shipments, or observed traffic.
The IEEE lists 30:5D:A6 as an MA-L assignment to ADVALY SYSTEM Inc. RFC 7042 explains that the Group and Local bits in the initial octet have special significance: assignments set the Local bit to zero and leave the Group bit unspecified; multicast identifiers may be constructed by turning on the Group bit. For this prefix, both bits are zero. The supplied evidence contains one prefix assignment.
