deepdig

pre-alpha

Network diagnostics that go deeper. DNS, TLS, mail, WHOIS, HTTP, blacklists, IP info — fast, detailed, streamed.

DNS

Parallel DNS diagnostics with propagation, DNSSEC, and history.

Certificate chain, expiry, protocols, OCSP, HSTS.

Domains (registrar, dates, status) and IPs (RIR allocation, ASN, abuse).

SPF, DKIM, DMARC, MTA-STS, TLS-RPT, BIMI, MX reachability + STARTTLS.

Response inspection, redirect chain, security headers, cookie flags.

Check an IP or domain against ~16 mail blacklists (Spamhaus, Barracuda, SpamCop, SORBS, …).

rDNS, ASN, CIDR, country, hosting/CDN classification — pure DNS (Team Cymru), no SaaS.

Paste a raw email. Received chain → hop waterfall, SPF/DKIM/DMARC verdicts, live SPF re-check against the source IP.

Certificate Transparency search via crt.sh — every cert ever issued for a domain and its subdomains.

HTTP/2 (ALPN) and HTTP/3 (QUIC/Alt-Svc) support plus CDN/edge fingerprinting from response headers.

IPv4/IPv6 network, broadcast, host range, netmask, wildcard and subnet splitting. Stateless.

Pronounceable or fully-random passwords. crypto/rand, no logs, no storage.
