An example covering this exact case: 9.0.0.0/8 is such a space, owned by IBM.

Some illicit use documented at www.ris.ripe.net :

9.184.112.0/20
9.186.144.0/20 , both from AS 3786 (dacom.co.kr, bora.net) , since at
least 2002/12/26.

IBM confirmed the bogosity of these announcements on 04/07, the routes
got withdrawn on 04/14.
