DNS-Abfrage
Löse A, AAAA, CNAME, MX, TXT, SRV, NS, CAA auf. Via Cloudflare DoH für Privatsphäre.
Über dieses Werkzeug
DNS lookup converts a domain name into the records (IP addresses, mail servers, verification strings, certificate-authority allow-lists) that the rest of the internet needs to talk to it. Where most lookup tools route through your local resolver — and therefore your ISP — this one runs over DNS-over-HTTPS so the network in front of you can't see what you're querying.
Useful before a domain transfer (verify the new nameservers picked up), during DNSSEC rollout, when debugging mail (SPF/DKIM/DMARC TXT records), or to inspect CAA constraints before requesting a new certificate.
