I can infer very strongly that the block has probably not been
allocated, or if it was, has not been properly listed in the directory
as allocated yet.

Look at the  DNS  delegation of  the  reverse DNS.   Y.arin.net
replies  NXDOMAIN for the 192.255.103.in-addr.arpa  zone  with
authority, indicating no rDNS delegation.

The  RADB  and  RIS   are  good  sources  to  query also.
