What is the ALL option?

ALL queries the common record types (A, AAAA, CNAME, MX, NS, TXT, SOA, CAA) in parallel and merges them into one priority-sorted list, so you see a domain’s full DNS footprint without switching types and re-querying.

How does reverse (PTR) lookup work?

Select PTR and enter an IP address instead of a domain. The tool builds the reverse pointer name (8.8.8.8 → 8.8.8.8.in-addr.arpa, or the ip6.arpa nibble form for IPv6) and resolves it to the hostname.

What does the DNSSEC badge mean?

It appears when Cloudflare returns the Authenticated Data (AD) flag, meaning the resolver cryptographically validated the response chain. No badge means the zone is unsigned or validation was not performed — not necessarily that anything is wrong.

Can I query a resolver other than Cloudflare?

Not yet — queries use Cloudflare’s DoH endpoint. For comparing resolvers or checking propagation across them, a command-line tool like dig (dig @8.8.8.8 example.com) is still the right call.

DNS Lookup

About DNS Lookup

Queries DNS records for any domain using Cloudflare’s DNS-over-HTTPS (DoH) resolver. Supports A, AAAA, CNAME, MX, NS, TXT, SOA, CAA, and SRV records, plus reverse (PTR) lookups from an IPv4 or IPv6 address. The ALL mode fetches every common record type in one query, MX and SRV results are sorted by priority, SOA/SRV/CAA payloads are parsed into labelled fields, and a DNSSEC badge appears when the resolver returns authenticated data.

Ten record types: A, AAAA, CNAME, MX, NS, TXT, SOA, CAA, SRV, and reverse PTR
ALL mode queries A/AAAA/CNAME/MX/NS/TXT/SOA/CAA in parallel and merges the results
Reverse PTR: enter an IPv4 or IPv6 address and it builds the in-addr.arpa / ip6.arpa pointer for you
MX and SRV records are sorted by priority; SOA, SRV and CAA payloads are split into labelled fields
Distinguishes NXDOMAIN, SERVFAIL, REFUSED and other RCODEs instead of a single generic error
DNSSEC badge shows when the resolver cryptographically validated the answer (AD flag)
Queries Cloudflare’s 1.1.1.1 DoH endpoint over HTTPS — no plaintext DNS; Copy all exports TSV
