I am not aware that IN-ADDR.ARPA and IP6.ARPA registries exist.  
They are not mentioned in the www.iana.org page.  We have to 
mention a registry, and the .ARPA registry seems to be the

No, I don't think it matters that they are not mentioned in the 
NTIA IANA contract.

We need IN-ADDR.ARPA and IP6.ARPA services.  We should mention the
