Query DNS records and WHOIS data with multi-provider support

DNS Provider

How it works: This tool queries DNS records via DNS-over-HTTPS from Google (8.8.8.8) or Cloudflare (1.1.1.1). Select "All Records" to query A, AAAA, CNAME, MX, NS, TXT, SOA, SRV, and CAA records in parallel. WHOIS data is fetched from the RDAP protocol (the modern replacement for traditional WHOIS). Results may differ between providers due to caching and propagation delays.

What is DNS Lookup?

Free online DNS lookup to look up DNS records for any domain.

Query A, AAAA, MX, TXT, CNAME, NS, and SOA records over public DNS-over-HTTPS. Use it to check MX records for email delivery, look up an SPF or DKIM TXT record, find a domain's nameservers, or verify a CNAME points where you expect. View results in a formatted table with TTL values and record data. Helpful for domain troubleshooting, email configuration verification, and DNS migration or propagation checks. No signup required.

How to Use DNS Lookup

1Enter a domain name (e.g., example.com)
2Select the record type to query (A, MX, TXT, etc.)
3Click Lookup to query DNS records
4View the results with record data and TTL values

Frequently Asked Questions

What DNS record types can I query?

A (IPv4 address), AAAA (IPv6 address), MX (mail servers), TXT (text records, SPF, DKIM), CNAME (aliases), NS (nameservers), and SOA (start of authority).

How does this work?

The tool resolves your query through a public DNS-over-HTTPS service that returns results in JSON format. This avoids browser CORS restrictions while giving you accurate, up-to-date record data.

Why don't I see the same records as my registrar?

DNS changes take time to propagate (up to 48 hours). Public resolvers may cache records for their TTL duration. If you just changed records, check back later.

How do I check my MX records for email?

Enter your domain and select the MX record type, then look up. The results list each mail server hostname and its priority value, lowest priority first. Cross-check these against your email provider's recommended MX records to confirm delivery is configured correctly.

Where do I find my SPF or DKIM record?

SPF and DKIM are stored as TXT records. Select TXT and look up your domain to see the SPF string (it starts with v=spf1). DKIM lives under a selector subdomain such as selector._domainkey.example.com, so query that exact name to read the DKIM key.
