As far as I can tell from IANA, the block 192/8 is allocated to ARIN. ARIN does not have a record of 192.255.103 being allocated to anybody.
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.
