As a software engineering lecturer, I use Domain Digger in my classes to help students understand how the internet works. The different interactive elements and maps help visualize various concepts and provide a fun way for students to learn about DNS interactively.

Everything dig, whois, and crt.sh give you — in one tab.
Live, uncached, and shareable. No install. No accounts. Just paste a domain.
- Live DNS lookups
- Every lookup runs in real time. We never cache results between requests.
- Every record type
- A, AAAA, CNAME, MX, TXT, NS, SOA, CAA, SRV — and the obscure ones too.
- Worldwide resolvers
- Compare answers from Cloudflare, Google, your ISP, or the authoritative servers — across regions around the world.
- WHOIS, decoded
- Registration, expiry, and ownership at a glance — no raw output to parse.
- Subdomain discovery
- Surface subdomains you didn't know existed. Built for security audits, recon, and attack-surface mapping.
- Certificate history
- Every SSL/TLS certificate ever issued for a domain, with issuer and validity dates.
