Using this prefix
This is a Company ID rather than a MAC address block. IEEE states that a CID cannot be used to generate universally unique MAC addresses, so it should not be used to infer the vendor of a device address.
For the matching rules, read the lookup methodology. For practical investigation steps, see how to identify a device from a MAC address.
