SAMSARA NETWORKS INC MAC prefixes identify registry assignments, not a device
Summary
- // what this is
- Samsara Networks is registered to MAC prefix
28:EA:5Band 2 more in the IEEE OUI database. When a device's MAC address begins with28:EA:5B, that block was registered by Samsara Networks — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- A prefix match identifies an IEEE registry assignment only. Group bit and Local bit are zero for each listed prefix; changing either changes the matching prefix. Suffix-value counts describe possible address values, not device or shipment counts.
About this vendor.
A MAC address beginning with 28:EA:5B, FC:DB:21, or C0:D3:91:E matches an IEEE assignment to SAMSARA NETWORKS INC; the match does not identify a particular device or product. The records list two MA-L prefixes and one MA-M prefix, for three assignments total. The displayed records provide no assignment dates.
The MA-L prefixes each fix 24 bits, leaving 24 bits for suffix values: 16,777,216 possible values per prefix. The MA-M /28 prefix fixes 28 bits and leaves 20 bits, or 1,048,576 possible suffix values. These are address-space counts, not counts of devices, shipments, or observed addresses.
For each listed prefix, the first-octet Group bit and Local bit are both zero. Under RFC 7042, changing either bit changes the prefix and therefore no longer matches that exact assignment. A captured address matching a prefix supports the registry match only; it does not establish deployment, traffic prevalence, current vendor identity, or safety. The supplied evidence does not establish company products, industry, country, website, or device categories associated with these assignments.
