DNS Lookup

Queries up to eight record types at once and shows each answer with its TTL: where a domain points, which mail servers receive its email, what SPF, DKIM and DMARC say, which nameservers are authoritative, and whether DNSSEC checked out.

Browsers cannot make DNS queries, so our server asks Cloudflare's public DNS-over-HTTPS resolver and passes the answer straight back. Nothing is cached on our side, which matters when you have just changed a record - although the rest of the internet may still hold the old answer until its TTL runs out.

Type an IP address and choose PTR for a reverse lookup; international domains are converted to punycode automatically.
