DNS Lookup Tool – Check DNS Records Online Free
About the DNS Lookup Tool
The DNS Lookup Tool queries a domain’s DNS records directly from public DNS servers using secure DNS-over-HTTPS (DoH). Enter any domain, choose a specific record type or check all of them at once, and the tool returns a clean, organized table showing A, AAAA, CNAME, MX, NS, TXT, SOA, PTR, SRV, and CAA records along with their TTL values.
This tool is built for developers, SEOs, and system administrators who need to verify DNS configuration during migrations, email setup, or troubleshooting. Once you’ve confirmed DNS records are correct, check the domain’s SSL certificate status with the SSL Checker, or verify its registration history with the Domain Age Checker.
eToolsKit Team tested this tool against domains with a wide range of DNS configurations — including multiple MX records, SPF/DKIM TXT records, and CNAME chains — across all four supported DNS providers to confirm accurate, consistent results.
How to Use the DNS Lookup Tool
- Enter a Domain or Hostname (e.g. example.com) — no need to include “http://” or “www.”
- Choose a DNS Server: Google, Cloudflare, OpenDNS, or Quad9.
- Select a Record Type: All, A, AAAA, CNAME, MX, NS, TXT, SOA, PTR, SRV, or CAA.
- Click Lookup DNS to run the query.
- Review the results table, grouped by record type when “All” is selected.
- Click Copy Results or Download .txt to save the output.
Example Usage
Input: Domain “example.com” with Record Type “MX” selected.
Output:
Name: example.com Type: MX TTL: 3600s Data: Priority: 10 | mail.example.com
Switching the Record Type to “TXT” instead reveals SPF, DKIM, or domain verification records without needing to run a separate command-line lookup.
Frequently Asked Questions
DoH encrypts DNS queries over HTTPS instead of sending them in plain text, making lookups more private and reliable than traditional DNS queries, and less prone to interception or tampering.
Google, Cloudflare, OpenDNS, and Quad9 are all public DNS resolvers. Results are usually identical for standard records, though propagation timing can occasionally differ slightly between providers right after a DNS change.
This usually means no records of that type exist for the domain, or the domain hasn’t propagated yet if DNS was recently changed. Try selecting “All” to check every record type at once.
TTL (Time To Live) shows how long, in seconds, a DNS record is cached before resolvers check for updates again. Lower TTLs mean changes propagate faster.
Yes, select “MX” as the record type to confirm your mail server priority and hostname are configured correctly before going live with email service.
Yes, this tool is completely free with no signup required.
