Brett, IMO it would have been better if ARIN had used the word  
"partners" instead of "contractors". I'm fairly sure that's what ARIN  
meant even if it wasn't what they said in the statement you quoted.  
ARIN will know that the other RIRs are not contractors to ARIN when it  
comes to reverse DNS space. As do the other RIRs. Who will presumably  
be happy to remind their cousins at ARIN of that fact.

The situation with DNS service for in-addr.arpa doesn't lend itself to  
soundbites. So I wouldn't worry too much about soundbites on a web  
page which by definition won't tell the whole story in painstaking  
detail. As I'm sure you know, some parts of the tree are managed by  
the other RIRs (who then have mutual arrangements for DNS service for  
"their" domains). [As an example, 195.in-addr.arpa is managed by the  
NCC and the zone's NSRRset includes name servers operated by APNIC and  
ARIN.] Other parts are handled by ARIN's name servers and its  
contractors (Neustar/Ultra IIRC). Then there's the AS112 project for  
RFC1918 space. And the unallocated or reserved space, etc, etc.

Now someone could explain all of this in fine detail. But would it  
help or hinder understanding of whar ARIN's doing wrt DNSSEC?
