A few years ago, I moved my domains to a registrar that supports DNSSEC for .co.uk domains when I realised that Google Cloud Platform supported DNSSEC and SSHFP records. That worked fine on GCP.
Now I am doing a lot of work with Oracle Cloud. According to their DNS FAQ, DNSSEC is not supported. However, their DNS hosting on Oracle Cloud supports DNSKEY, DS, CDS and CDNSKEY as well as SSHFP records.
So how can I set SSHFP records for Oracle Cloud instances? If I keep the DNS hosting done on Google Cloud, can I use CDS/CDNSKEY records (or whatever) as a child zone on Oracle DNS?
I currently have DNS being done on Google Cloud, with NS records for specific hosts pointing at Oracle Cloud. There are NS records for every host. It works, but I don't know if there's a better way to do this, and DNSSEC obviously doesn't work.
