@jpmens Passive DNS databases do it, no?

@bortzmeyer @jpmens - I guess pDNS databases are too restricted to access. I see the advantage of an open database for such information.

My best guess for now would be openintel.nl, which has a massive #opendata program.

@jpmens Yes. Domain Tools' DNSDB is very expensive. May be the one at CIRCL.lu ?

@bortzmeyer "Access to CIRCL Passive DNS is restricted to trusted partners both in Luxembourg and abroad. If you are interested in gaining access, please contact us and provide details about your affiliation and the intended use of the Passive DNS data."

This is all quite different from querying a name on crt.sh

@jpmens I don't remember how I got my account but I'm reasonably sure that the process was quite lightweight.
Unfortunately, I just tested and they don't store DNSSEC material 😠
