DNS lookup and dig-style record search

Query public DNS records for any domain—A, AAAA, MX, TXT, NS, CNAME, or SOA—with tab-separated output similar to dig. Choose Cloudflare or Google public resolvers over DNS-over-HTTPS from your browser.

Lookup DNS Now helps administrators, site owners, and students verify that a domain publishes the records they expect before cutover or troubleshooting. Enter an apex or subdomain, pick a record type, and read TTL plus_rdata in a copy-friendly block. The tool does not perform authoritative zone transfers, reverse DNS for arbitrary IPs, or DNSSEC chain validation—it mirrors what a public resolver returns at query time, which is what most browsers and mail systems use in practice.

How to use this DNS lookup tool

1. Type a domain name (example.com or mail.example.com) without a path.
2. Choose the record type you need—A/AAAA for web, MX for mail, TXT for verification strings.
3. Pick a public resolver (Cloudflare or Google DNS-over-HTTPS).
4. Press Look up DNS and copy the dig-style lines for tickets or runbooks.
5. Re-run after TTL expires if you are waiting for DNS propagation.

Examples

• Check web host: Look up A and AAAA for www.example.com after changing hosting.
• Verify email: Query MX and TXT to confirm mail routing and SPF/DMARC presence.
• Delegation audit: Compare NS answers against your registrar glue before a migration.

Limitations

• Results reflect the selected public resolver, not hidden authoritative-only views.
• Some resolvers rate-limit or truncate large responses; retry or switch resolver if needed.

FAQ

Is this the same as running dig on my laptop?

It is similar: you specify a name and type and receive RDATA. Here, the query goes to a public DoH endpoint rather than your local recursive resolver.

Do you store the domains I look up?

No server-side logging is performed by this static app. The resolver you choose will see the query under its own privacy policy.

Why do I get no answers?

The name may not exist, the type may be empty, or the resolver may be blocked on your network. Try another record type or resolver.

Can I look up reverse DNS (PTR)?

Not in v1. Enter hostnames only; reverse IP lookup may be added later.
