DNS records
Every DNS record we can find for a domain, each with a plain comment, ready to export to Excel.
DNS records are the settings that tell the internet where a domain's website, email and other services live. They are kept at the DNS provider, which is often the registrar, the hosting company or Cloudflare.
DNS can't list all records of a domain. This page asks for the names nearly every domain uses (the domain itself, www, mail, autodiscover, DMARC, common DKIM keys and more). A subdomain nobody links to can stay hidden.
