Benefits
Good to know about this tool
Looks up a domain's public DNS records live (A, AAAA, MX, NS, CNAME, TXT) and displays them clearly.
DNS misconfigurations are a common cause of unreachable websites or failed email delivery.
- Check A records are up to date after a server move
- Verify MX records before switching email providers
- Quickly see which nameserver serves a domain
- Allow a few hours for propagation after DNS changes
- Compare multiple resolvers if results look unclear
Frequently Asked Questions
Why do I see different values than my own PC?
DNS changes take time to propagate globally (depends on TTL) — different resolvers can temporarily show different values.
Are my lookups stored?
The request goes directly from your browser to Cloudflare's public DNS resolver — not through our server.
