Palmmicro Communications MAC prefixes: registry identity only
Summary
- // what this is
- Palmmicro Communications is registered to MAC prefix
00:18:1Fand 1 more in the IEEE OUI database. When a device's MAC address begins with00:18:1F, that block was registered by Palmmicro Communications — the OUI identifies the maker of the network hardware, which is not always the brand on the device. - // analyst note
- The two MA-L records use different registered organization names; the evidence does not establish whether they are one legal entity. Both prefixes have 24-bit matching boundaries, with 24 suffix bits and 16,777,216 mathematically possible suffix values each. In the first octet of each exact prefix, Group and Local bits are zero. A match establishes assignment correspondence only, not observed deployment or product identity.
About this vendor.
A MAC address beginning 00:18:1F or 00:09:45 matches an IEEE MA-L assignment registered to Palmmicro Communications or Palmmicro Communications Inc, respectively; the records do not establish a device category or product for either prefix. A prefix match identifies a registry assignment, not a particular device, operating system, current legal identity, or security state.
Each is a 24-bit prefix, leaving 24 bits for suffix values: 16,777,216 possible values per prefix. That is a mathematical address space, not a count of devices or shipments. These are two separate assignments; they do not establish one shared /24 base.
In both prefixes, the first octet is 00: its Group bit and Local bit are zero. RFC 7042 explains that assignments use the Local bit set to zero and leave the Group bit unspecified, with multicast identifiers formed by setting the Group bit. For these exact prefixes both bits are fixed; changing either produces a different prefix. A captured matching address supports the assignment match only, not product attribution or deployment.
