DNS Lookup
NetworkQuery DNS records (A, AAAA, MX, TXT, NS, CNAME, SOA, CAA) via Google or Cloudflare DoH and inspect name, type, TTL and data in one click.
About DNS Lookup
DNS is the internet's phonebook — turning domains into IPs, routing mail via MX, stashing verification in TXT. When troubleshooting resolution, validating config changes or debugging mail delivery, you need a tool that queries record types on demand. This tool queries A, AAAA, MX, TXT, NS, CNAME, SOA and CAA records via Google and Cloudflare DNS-over-HTTPS endpoints, showing name, type, TTL and data. Requests go directly to the DoH provider, not relayed through this site. Tip: Bookmark this tool for quick access during network troubleshooting. All queries are made directly from your browser — no command-line tools required.
How to Use
- Open the DNS Lookup tool page
- Enter or paste your data into the input area
- View the real-time results and use the copy button to get the output
Use Cases
- Resolution troubleshooting — Check A/AAAA records to confirm the domain points at the right IP and root-cause "site won't load".
- Mail config audit — Check MX and TXT (SPF/DKIM) to fix rejected or junked email.
- Migration validation — Compare old and new records and TTL after a DNS change to confirm global propagation.
- Certificate authorization — Check CAA to ensure only designated CAs may issue certs for the domain.
- Delegation mapping — Check NS and SOA to clarify subdomain delegation and zone master/slave.
- Verify CDN mapping — Resolve A/AAAA records to confirm the domain points to the expected CDN edge IPs after a provider switch.
- Detect domain takeover — Check CNAME records for dangling DNS that could lead to subdomain takeover by an unregistered target.
FAQ
Which provider handles the query?
You can switch between Google and Cloudflare; requests go directly to the DoH endpoint (dns.google or cloudflare-dns.com), not relayed by this site.
Why "No records found"?
The domain has no record of that type — possibly unconfigured or wrong type selected; try NS or SOA to confirm the domain exists.
What unit is TTL?
Seconds. It is how long the record may be cached; after a change, expect roughly one TTL for global propagation.
Can my queries leak?
DoH is HTTPS-encrypted so third parties can't easily snoop, but the DoH provider itself sees the request.
Can it do reverse (PTR) lookups?
This release focuses on forward records; PTR reverse lookups aren't provided — use dig -x on the command line.
Any browser compatibility requirements?
This tool works in all modern browsers (Chrome, Firefox, Edge, Safari). No plugins or extensions required.
Can I use it offline?
After initial load, most features work offline. The core logic runs entirely in your browser with no network dependency.
