Nokia Solutions (Shanghai) Co.,Ltd. — vendor identified; device type unknown
Summary
- // what this is
- Nokia Solutions is registered to MAC prefix
90:F0:4Cand 1 more in the IEEE OUI database. When a device's MAC address begins with90:F0:4C, that block was registered by Nokia Solutions — the OUI identifies the maker of the network hardware, which is not always the brand on the device.
About this vendor.
A MAC address beginning with 90:F0:4C or BC:93:88 matches an IEEE MA-L assignment to Nokia Solutions (Shanghai) Co.,Ltd.; the assignment does not identify a device type. The records list two 24-bit prefixes, each leaving 24 bits for the remaining address. The IEEE records supplied here do not provide assignment dates.
RFC 7042 explains that the first octet’s Group bit (0x01) and Local bit (0x02) have special significance. For both listed prefixes, hexadecimal arithmetic gives 90 & 0x03 = 0 and BC & 0x03 = 0, so both bits are zero in the exact literal prefixes. Addresses matching those prefixes share the first 24 bits; the remaining 24 bits can take 16,777,216 possible values per prefix. That is a mathematical suffix space, not a count of devices or shipments.
A captured address can establish a prefix match, but not a particular product, operating system, current legal identity, or security status.
