Won't DNS records reveal who Satoshi is? Fine, we don't know who he is. I get that. But he did register bitcoin.org, and as a result had to use a credit card. So the original domain registrar must know who he is, no?
Assuming that Satoshi himself registered the domain with his or her own personal information, and/or used a credit card tied to his or her real name, then it is likely that the registrar maybe have knowledge of the real identity.

HOWEVER,


It is not known if Satoshi used his or her real name to register.
It is not known if Satoshi used his or her personal payment information when registering.
It is unlikely that a registrar that specializes in privacy would ever divulge the above information or even its existence without a court order.
It is possible that the registrar may not have retained records dating back to then, so it is possible that the above information was known but is no longer retrievable.


DNSHistory.org began tracking bitcoin.org in early 2011, well after Satoshi exited. It does not track registrant information. WhoisRequest.org tracks NS back to September 2008, but only tracks nameserver changes. Who.is yields the known fact that the domain was registered with the AnonymousSpeech registrar and the registrant information as DigiRock, a Japanese domain registrar and hosting provider. This was likely a proxy registration.
