DNS toolbox
Inspect DNS from your browser.
A fast, browser-first DNS toolbox. Resolve a name, diagnose propagation and DNSSEC, investigate ownership and reputation, then save a shareable snapshot.
DNS lookup
Resolve a name to one record type — A, AAAA, MX, TXT, and more.
Propagation
Compare the answer across public resolvers to see whether a change has propagated.
DNSSEC
Check whether a domain is DNSSEC-signed and validates, with its chain of trust.
Reverse PTR
Find the hostname (PTR) registered for an IP address.
RDAP / WHOIS
Look up registration and ownership data for a domain or IP.
Mail health
Check a domain's MX, SPF, DMARC, and DKIM email records.
Discovery
Probe common subdomains for live records.
All records
Fetch every common record type for a name in one request.
Delegation trace
Walk the delegation path from the top-level domain down to the authoritative nameservers.
Blocklist (DNSBL)
Check whether an IP address is listed on common DNS blocklists.
Run a query above and results will appear here.
JSON API & automation endpoints
The browser panels use these endpoints; automation can call them directly.
