Of course the IEEE Registration Authority is the authoritative source
for Ethertype assignment information. See It is
somewhat of a historic accident that there is an informational listing
of historic and IETF relevant Ethertypes on the IANA web

If you have a need for an Ethertype, you should reference RFC 7042 (Section 3) and the IANA's IEEE 802 Numbers page (  for more information.  Donald Eastlake (primary) and Juan Carlos Zuniga (secondary) are the IANA-designated experts for Ethertypes.
