Uh, no.  Since arpa is a TLD, it'll find you the RDAP server for the .arpa 
TLD, which will tell you something about the people at IANA who manage it. 
As I said, this is probably not the question you meant to ask.  It's worth 
noting somewhere that asking about the rDNS name associated with an IP 
address is not the same as asking about that IP address.  Name and number 
queries are different, different question syntax and different answer 
syntax.

This is the IETF, so we can't force anyone to do anything.  But assuming 
the RIRs are willing, we could put in language along the lines of what I 
suggested a couple of messages ago.
