1Net Corporation — MAC prefix identifies its IEEE registry assignment
Summary
- // what this is
- 1Net is registered to MAC prefix
00:30:70in the IEEE OUI database. When a device's MAC address begins with00:30:70, that block was registered by 1Net — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- A captured address matching 00:30:70 establishes a match to this MA-L registry assignment, not a specific device, product, current legal identity, or security state. The first-byte Group and Local bits are both zero and fixed for this literal prefix. The 24 remaining bits permit 16,777,216 suffix values; this is address-space capacity, not an observed device or shipment count.
About this vendor.
A MAC address beginning with 00:30:70 matches an IEEE MA-L assignment registered to 1Net Corporation. This identifies the registry entry associated with the prefix; it does not establish which device, product, or current organization used a captured address.
The prefix is 24 bits long, leaving 24 suffix bits and 16,777,216 possible suffix values. That number describes the address space under the prefix, not a count of devices or shipments. The Group bit and Local bit in the first byte 00 are both zero. For this exact literal prefix match, those bits are fixed; changing either bit produces a different prefix.
RFC 7042 explains that 48-bit MAC identifiers commonly use an initial three-octet OUI followed by three additional octets, and that the Group and Local bits have special significance. The available record supports the company name and assignment only; it does not establish products, industry, or device categories for this prefix.
