Resolves A, AAAA, MX, NS, TXT, CAA and SOA, reads the WHOIS record of the responsible registry, checks SPF, DMARC and known DKIM selectors, opens a TLS handshake for issuer, validity, chain and SAN list, and collects subdomains from Certificate Transparency. Fields that a registry refuses to answer are reported as unknown, never guessed.
