Wildcards are a good start, or at least they appear so on the surface. Unfortunately, the vagueness of their definition and various implementations of wildcards would make this a poor choice. Not to mention, wildcards will severely fragment the namespace once real PTRs are introduced creating a rather fine mess. This would also add another level of complication and restrict the layering capabilities we are attempting to introduce and would inevitably prove far more problematic and resource intensive than you might expect, simply to compensate for all the fragmentation. > > > Forget for a moment about IPv6.

We are looking for a vendor agnostic solution and feel a standards body is ultimately right choice.

For NSEC3 I suspect this is not feasible. > Unfortunately, there are lots of ways DNS is abused to provide an undue prejudice against huge swaths of mild-mannered, legitimate IPs. While our solution (NPN) offers the same opportunity for abuse, it doesn't preemptively defeat other options, such as online signing where BULK generated records are *exactly* like any other record.
