Re: [weirds] I-D Action: draft-hollenbeck-dnrd-ap-query-00.txt

I used to be in Internet LE. Out of band may not be sufficient for legal reasons or because of timeliness. It's obviously better than nothing and often all that's available currently but I thought I should clarify the point.

FWIW, relative old timers in Internet LE miss the days when Whois records often included registrant ID numbers.

-1.

While I can see the usefulness of such an information in specific criminal investigations, I think the registry or registrar could provide this information out of band to the relevant law enforcement authorities, when asked properly.

As mentioned already, IP addresses are considered as personal data under some jurisdictions.

If anything, this thread also shows the need to come up with an authentication framework. It is not just a nice to have option, but should be an integral part of the deliverables.

In a searchable world, sometimes all you have is the IP of the name server that's resolving the malicious/harmful domain. So asking "what other domains host zone files at this IP?", "who registered those domains?", and "what registrar is sponsoring the registrations?" are all useful crumbs that often help you identify names used by in a campaign, or the registrant names used in association with a criminal enterprise.
