48-bit Ethernet address prefixes (the first 24 bits) are assigned by the
IEEE from what I can tell. One or more prefixes are assigned to various
different vendors.
The prefixes and their owners used to be tracked in RFC-1700 ("Assigned
Numbers") but this is woefully out of date. This site here seems to
be a little more up to date:

We get this stuff all the time. Usually it's an old, managed or semi-managed
FDDI hub or something similar. Or sometimes a serial port concentrator (LAT
in DEC-speak.)
