Description
deepdig is a free toolbox of network diagnostics built for sysadmins, DevOps engineers and hosting operators — the checks you run every day, faster and more detailed, with no account and no ads.
Enter a domain, IP or paste raw data. Checks run in parallel on our servers and results stream in live, each finding graded by severity with a plain-English explanation of why it matters.
TOOLS
DNS diagnostics — records, delegation and glue consistency, full DNSSEC chain validation from the root, propagation across 18 public resolvers, and a hop-by-hop recursion trace
SSL/TLS — certificate chain, expiry, hostname match, trust, protocol versions, HSTS
WHOIS — registrar, dates, EPP status codes for domains; RIR allocation, ASN and abuse contacts for IPs
Mail tester — SPF, DKIM, DMARC, MTA-STS, TLS-RPT, BIMI, MX reachability and STARTTLS
Email header analyzer — paste a raw email, get the Received chain as a timed hop-by-hop trace with SPF/DKIM/DMARC verdicts
DNSBL / blacklists — check IPs and domains against major blocklists, Spamhaus included
HTTP headers — security headers, redirect chain, cookie flags, server fingerprint
HTTP/3 — ALPN negotiation, Alt-Svc advertisement and CDN detection
IP info — ASN, announced prefix, rDNS, country and hosting classification
Certificate Transparency log search
Subnet/CIDR calculator and a password generator
WATCHES — GET NOTIFIED WHEN THINGS CHANGE
Put a domain or IP on watch and deepdig re-checks it for you. You get a push notification only when something actually changes: a certificate crossing 14, 7 or 1 day to expiry (and a recovery notice when it renews), a new blacklist listing or a delisting, or a changed DNS record set. No noise, no daily digests — alerts only on real transitions.
