In this case it is both, so I cannot say for sure which.  Let me
explain.  Neustar is both the Registry and Registrar in this case, as
this is a 4th-level Locality .US domain that is delegated directly from
the .US ccTLD.  Once there are other .US Registrars offering DNSSEC
services available, we'll see if it is just the way Neustar as a
Registrar implemented it, or if it is a Registry restriction they have
imposed.  Neustar does not yet offer a list of Registrars which offer
DNSSEC services, and I would not use one as my 4th-level Locality domain
is free, forever.
