Resolver comparison
Compare the same query through Cloudflare (Bit Happens API) and Google Public DNS. Different TTL values are normal; different answer data can indicate propagation, load balancing or resolver policy.

Frequently asked questions
Which records can I query?
A, AAAA, CNAME, MX, NS, SOA, TXT, CAA, DS and PTR. For PTR, enter an IPv4 or IPv6 address and the portal builds the reverse name.
Which resolver does DNS Lookup use?
Cloudflare DNS over HTTPS (1.1.1.1). The DNS Explorer can also compare with Google Public DNS to see whether both already return the same answer.
Why does my computer get a different answer?
It may use your ISP or company resolver, or a local cache. Each resolver keeps the answer for the record TTL, so recent changes show up at different times.
What does an authenticated (AD) answer mean?
The resolver validated the answer with DNSSEC. If the domain does not use DNSSEC the answer is still normal, just not authenticated.
How do I find every subdomain of a domain?
DNS does not list subdomains. Use the Subdomains mode of the DNS Explorer, which combines Certificate Transparency with passive DNS checks.
