adp Gauselmann GmbH: MAC prefix identification
Summary
- // what this is
- adp Gauselmann is registered to MAC prefix
00:0E:87in the IEEE OUI database. When a device's MAC address begins with00:0E:87, that block was registered by adp Gauselmann — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- The first-octet Group bit and Local bit are both zero for this exact prefix. The prefix matches on the first 24 bits; the remaining 24 bits permit 16,777,216 possible suffix values, which is not an observed device or shipment count. A prefix match establishes the registry assignment only.
About this vendor.
A MAC address beginning with 00:0E:87 matches an IEEE MA-L assignment to adp Gauselmann GmbH. The assignment identifies the registry holder; it does not establish which device or product used an address, whether that address is deployed, or who operates it today.
This is a 24-bit prefix, so matching requires the first three octets (00:0E:87). The remaining 24 bits allow 16,777,216 possible suffix values; that mathematical range is not a count of devices or shipments. For this exact prefix, the first-octet Group bit and Local bit are both zero. Changing either bit changes the prefix and therefore no longer matches this exact assignment.
RFC 7042 describes 48-bit MAC identifiers as an initial prefix followed by additional bits, and explains the Group and Local bits.
- Device category
- Unknown; the evidence does not map a device category to this exact prefix.
