Tilgin AB MAC Prefixes: Vendor Identification

A MAC address beginning with 00:02:61 or 64:20:9F matches an IEEE MA-L assignment to Tilgin AB. That match identifies the registry assignee; it does not establish which device made the address, whether it is deployed, or who currently operates it.

Both entries are 24-bit prefixes, leaving 24 bits for suffix values. Each therefore has 16,777,216 possible suffix values, a mathematical address space rather than a count of devices or shipments. The supplied records do not establish device categories, products, industry, or a company website.

For each literal prefix, the first octet has Group bit 0 and Local bit 0. Those bits are fixed for the exact prefix. Turning either on changes the prefix and no longer matches it literally. RFC 7042 describes the Group and Local bit significance in 48-bit MAC identifiers; a captured address can support a prefix match, but not identify a particular product or device.
