Publisher-provided text

• dns_lookup Look up DNS records of one type (A, AAAA, CNAME, MX, NS, SOA, TXT, SRV) for a domain using public resolvers.
• dns_propagation_check Query a domain on about 40 public resolvers in different regions and report which ones return which answers, to see whether a DNS change has propagated.
• dnssec_check Validate the DNSSEC chain of trust for a domain from the root down (DS, DNSKEY, RRSIG) and report each zone as secure, insecure or broken.
• mx_lookup List the mail exchanger (MX) records of a domain with their preferences.
• spf_lookup Fetch the SPF record of a domain from its authoritative name server and list its mechanisms (ip4, ip6, include, redirect, all).
• spf_validate Validate the SPF record of a domain: syntax, single-record rule, DNS lookup count (limit 10), void lookups, includes and the all mechanism.
• domain_whois WHOIS registration data for a domain: registrar, dates, status and name servers (personal contact data is redacted by registries).
• domain_expiry Registration and expiry dates of a domain, with the time remaining before it expires.
• ssl_certificate_check Connect to a domain on port 443 and report the certificate chain: subject, issuer, validity dates, days remaining, SANs and chain details.
• ping Ping a public host from httpfy servers (4 ICMP echo requests) and report packet loss and round-trip times. Useful to test reachability from outside your own net
• traceroute Traceroute to a public host from httpfy servers (up to 10 hops). Internal hops of httpfy's own network are masked.
• ip_whois WHOIS / registry data for a public IPv4 address: ASN, network range, owner organisation and registry.
• ip_blacklist_check Check whether a public IPv4 address is listed on common DNS-based blocklists such as Spamhaus, Barracuda and SpamCop.
• mac_vendor_lookup Identify the manufacturer registered for a MAC address prefix (OUI) using the IEEE registry.
• asn_lookup Look up the autonomous system (ASN) for a public IP address, or details for an ASN such as AS15169: name, country, announced prefixes and address counts.
• bimi_check Check the BIMI record of a domain, whether DMARC meets BIMI requirements, and whether the SVG logo and certificate URLs are reachable and well formed.
• caa_check Find the CAA records that apply to a domain (climbing to parent domains per RFC 8659) and list which certificate authorities may issue certificates.
• certificate_transparency_search List certificates logged in Certificate Transparency for a domain (via crt.sh): issuer, validity window and names, with a summary by issuer.
• dkim_check Check DKIM public keys for a domain. With a selector it checks that selector; without one it probes common selectors. Reports key type and RSA key length and fl
• dmarc_check Find and explain the DMARC record of a domain (policy, pct, rua/ruf, alignment) and flag weaknesses such as p=none or missing external report authorization.
• dns_report Full DNS report for a domain: delegation from the root, every authoritative name server checked individually (reachability, recursion, TCP, consistency), SOA va
• domain_health_report Grade a domain A to F across 11 checks (name servers, SOA, DNSSEC, MX, SPF, DMARC, CAA, HTTPS certificate, HTTP to HTTPS redirect, HSTS, IPv6), with a reason an
• mta_sts_check Check MTA-STS (TXT record and the HTTPS policy file, mode and MX patterns) and the TLS-RPT reporting record for a domain.
• port_check Check whether one TCP port on a public host is open, closed or filtered when tested from httpfy servers on the internet.
