The DKIM public key is technically a TXT record. Some people do use a CNAME version, but then yeah, you put in the hostname of the real server (real DNS entry) that has the TXT entry. So in your case, you’re probably looking to paste that key value into the TXT record.
Your selector is “k1” in this example. That sounds right based on Googling the iONOS instructions, I think.
