Heho, > That is a real cool project! Thanks. And mostly running on openbsd. ;-)
> I didn't knew signed rDNS is possible. Yeah; It actually is: https://dnssec-analyzer.verisignlabs.com/3.197.191.195.in-addr.arpa But many orgs don't sign their rDNS, which makes it hard for endusers to get signed rDNS on their VMs. No clue how openbsd.amsterdam is doing in that regard... ;-) With best regards, Tobias
