Yes, that sounds right.
It looks like ARIN has no nameservers listed for your block.

Is that somewhat correct?

Part of ARIN allocating a block to you is authoritative namesevers for the in-addr.arpa zone. You could host rDNS anywhere you want, as long as ARIN points to those nameservers as authoritative for your block. Are you saying this customer is using IP space from another provider, or has their own? You would need to get the owner of that block to delegate DNS to you for that IP address or subnet. I remember once I was doing hosting for a customer who had a T1 from AT&T, and AT&T policy was not to provide rDNS for AT&T blocks assigned to a customer if that customer’s domain was hosted elsewhere. Actually, what AT&T did was to delegate rDNS to my nameservers without telling me first, which resulted in constant lame delegation log entries.

( Ducks) I'm assuming not? Anyway to resolve their request with hosted DNS or through Arin's website ?
