Why is Fing using MAC address beginning with F0:23:B9 ?

As per https://www.iana.org/assignments/ethernet-numbers/ethernet-numbers.xhtml
90-01-01 .. 90-01-FF are unassigned
IEEE assigns 802 numbers including  ORGANIZATIONALLY UNIQUE IDENTIFIERS https://www.iana.org/assignments/ieee-802-numbers/ieee-802-numbers.xhtml

    Fing is using a registered address as far as I can see...  See screenshot below..  (Domotz was Fing)

    Interesting however, "a list of OUIs and MAC addresses compiled from a number of sources."
    Seems like their list is by discovery not by official assignment.
    I strongly suggest you contact IEEE. https://standards.ieee.org/products-services/regauth/index.html
    Note that the separation of bluetooth MACs is maintained due to the requirement that they all have the two most significant bits on i.e. they all being with C,D,E or F

    I understand the difficulty regarding devices already deployed but there is no reason to continue with that address.
