Which of a custom domain’s DNS records are in place, and who hosts its DNS

For a domain whose DNS is elsewhere. The records are looked up at the domain’s own nameservers (no cache in between), so a record shows here as soon as the provider serves it. zone is the domain’s DNS zone (example.com for app.example.com) and each record’s host is relative to it ("@" for the zone itself), the form most DNS providers ask for. status: ok, missing, or wrong (found lists what is there instead). provider names the DNS host, with a link to its DNS settings and tips (id other, named by the nameservers’ own domain, when it is not one Orgo knows; null when no nameservers answer). extra lists what would get in the way: another A or AAAA record at the name (some visitors would reach the old address), or a CAA record that leaves out Let’s Encrypt (no HTTPS certificate). A domain bought through Orgo answers provider orgo (Orgo DNS), where Orgo set the records. Changes nothing; POST /verify turns the domain on. 30 checks a minute per account.
