Since 2002, the RADB has included entries that originate with ARIN. The RADB
also includes records from numerous other databases. That's what the
'source:' tag is for.

Are you saying the ISP only accepts entries they can pull from the RADB? Or
only entries that originate with the RADB? If the former, you're fine. Your
ARIN records are in the RADB.
