DNS Lookup
Look up a domain's A, AAAA, MX, TXT, NS and CNAME records in real time.
Frequently Asked Questions
Is the DNS Lookup really free?
Yes — unlimited use, no signup, no credit card. We built these tools to help you audit sites without paying for a data subscription.
Does this tool store or share the URLs I check?
No. Each check runs live and we don't save your input. We keep a short-lived rate-limit counter (by IP) purely to prevent abuse; it is not linked to your results.
How accurate are the results?
This tool reads live, public data directly from the page or domain you enter — it does not rely on a paid third-party database, so it reflects exactly what is publicly visible right now.
DNS records are the behind-the-scenes settings that make a domain work — where its website is hosted (A/AAAA records), where its email goes (MX records), which nameservers are authoritative (NS records), and various verification and configuration entries (TXT records). This tool looks up a domain's live DNS records, useful for troubleshooting, verifying configuration, or researching how a site is set up.
How to Use This Tool
Enter a domain and click Look Up DNS. The tool queries the domain's current DNS records across the common record types.
What This Tool Checks
A records (IPv4 address), AAAA records (IPv6), MX records (mail servers), TXT records (verification/SPF/DKIM and misc.), NS records (nameservers), and CNAME records (aliases).
Understanding Your Results
A records tell you the server IP hosting the site. MX records reveal the email provider (Google Workspace, Microsoft 365, etc.). TXT records often contain SPF and DKIM entries that affect email deliverability, plus domain-verification tokens for various services. NS records show who controls the domain's DNS.
How to Fix Common Problems
If you're troubleshooting your own domain — a site not loading, email not arriving — compare the live records here against what your host or email provider says they should be. Remember DNS changes can take time to propagate globally (from minutes to 48 hours), so a recent change may not show everywhere immediately.
SEO Best Practices
Keep a documented record of your domain's intended DNS configuration so you can spot unauthorized or accidental changes. Ensure you have proper SPF, DKIM, and DMARC TXT records configured for email deliverability — misconfigured email authentication is a common, invisible cause of emails landing in spam.
Example
Looking up a domain shows its MX records point to Google's mail servers and a TXT record contains a Google site-verification token — quickly confirming the business uses Google Workspace.
Common Mistakes to Avoid
Don't panic if a change you just made isn't visible yet — DNS propagation takes time. Don't edit DNS records without knowing what they do; a wrong MX or NS change can take down email or the whole site.
