• dns_lookup Looks up DNS records (A, AAAA, CNAME, MX, NS, TXT, SOA or CAA) for a domain through a public resolver. Other record types and specific nameservers are handled b
• dns_propagation Asks several public resolvers around the world for the same record and reports whether they agree, which shows whether a DNS change has propagated.
• dnssec_check Checks whether a domain is signed with DNSSEC and whether its chain of trust (DS and DNSKEY records) is consistent.
• mx_check Lists the mail servers (MX records) of a domain with their priorities and checks that they resolve.
• spf_check Reads and validates a domain's SPF record: syntax, the 10-lookup limit, includes and the final policy.
• dmarc_check Reads and validates a domain's DMARC record: policy, reporting addresses, alignment and percentage.
• dkim_check Looks up and validates a DKIM public key. Give the selector if you know it; otherwise the common selectors are tried.
• bimi_check Checks a domain's BIMI record and logo (SVG) for brand indicators in email clients.
• email_blacklist_check Checks whether a mail server IP address or a domain is listed on public DNS blocklists. Give exactly one of ip or domain.
• email_deliverability_report Scores a domain's email setup (MX, SPF, DKIM, DMARC, MTA-STS, TLS-RPT, BIMI, blocklists) and lists what to fix. Covers the whole email setup in one call, for a
• whois_lookup Looks up a domain's registration data over RDAP: registrar, creation, expiry and update dates, status and nameservers. Not every country code TLD publishes RDAP
• hosting_check Finds out who hosts a website: the IP addresses, the network and organisation behind them, the nameservers and any CDN in front.
• redirect_check Follows a URL's redirects hop by hop and reports each status code, the final address and problems such as loops, long chains or http-to-https gaps.
• http_headers_check Fetches a page and reports its response headers, with a review of the security headers (HSTS, CSP, X-Frame-Options and others) and cookie flags.
• website_down_check Checks whether a website is reachable from Cloudflare's network: DNS first, then one request. Separates 'does not resolve' from 'will not connect' and 'answers
• robots_txt_test Fetches a site's robots.txt and tests whether a given crawler may fetch a given path, following RFC 9309. Also lists the Sitemap lines and parser warnings.
• sitemap_check Finds a site's XML sitemap (from robots.txt or the usual addresses), then validates it against the sitemaps.org protocol and Google's rules. Reads at most 5 MB;
• url_status_check Fetches up to 10 URLs from one site and reports each one's final status code, redirects, content type and X-Robots-Tag. Useful for spot-checking pages listed in
• ip_lookup Describes a public IP address: the announced prefix and AS number, the network's name, country, registry and the reverse DNS name.
• asn_lookup Looks up an AS number (like AS13335) in Team Cymru and RDAP: the network's name, organisation, country, registry and registration dates. An IP address is mapped
• reverse_dns Finds the PTR (reverse DNS) name of an IP address and checks that the name resolves back to the same address (forward-confirmed reverse DNS), which mail servers
• ssl_check Makes live TLS connections to a host and reports the certificate chain, expiry, protocol versions, cipher strength and common misconfigurations. Ports 443, 8443
• smtp_test Connects to a domain's mail servers (MX) on port 25, says EHLO, tries STARTTLS and reports banners, TLS and reverse DNS. It never sends mail.
• dig Sends a DNS query like the dig command, to Cloudflare, Google, Quad9 or a nameserver you name, and returns the full answer with flags and sections. Supports man
• dns_trace Follows a name from the root servers down through the TLD to its authoritative nameservers, like dig +trace, and shows each delegation step.
• traceroute Traces the network path from the probe server in Germany to a host, showing each hop's address and round-trip times.
• http3_test Checks whether a site supports HTTP/2 and HTTP/3 (QUIC): ALPN negotiation, the Alt-Svc header and a live QUIC handshake probe.
• ttfb_test Times three requests to a web address from the probe server in Germany: DNS, connect, TLS, time to first byte and download. Results are never cached.
