Xpeed, Inc. — vendor identification is limited to registry assignments
Summary
- // what this is
- Xpeed is registered to MAC prefix
00:03:20and 1 more in the IEEE OUI database. When a device's MAC address begins with00:03:20, that block was registered by Xpeed — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- An exact prefix match identifies the MA-L registry assignment. Both prefixes are 24 bits, leaving 24 suffix bits and 16,777,216 possible suffix values per prefix; this is not a device or shipment count. Their first-byte Group and Local bits are each zero. Changing either bit changes the prefix and breaks the exact assignment match. Registry assignment alone does not identify a device, product, current vendor identity, or security state.
About this vendor.
A MAC address beginning 00:03:20 or 00:50:7A matches an IEEE MA-L assignment to Xpeed, Inc.; the supplied records do not establish which device or product uses either prefix. Registry attribution identifies the recorded assignee, not a specific device, current vendor identity, or security state.
Both are 24-bit prefixes, leaving 24 bits for suffixes: each has 16,777,216 possible suffix values. That is a mathematical address-space count, not a count of devices or shipments. A captured address can establish a match to the first three bytes, but does not identify a particular product.
For both prefixes, the first-byte Group bit and Local bit are zero. RFC 7042 explains these bits' MAC-address significance. Because the prefix's first byte is fixed, changing either bit changes the prefix and no longer matches the exact assignment. The IEEE CSV records provide no assignment dates.
