DNS Lookup

Look up A, MX, TXT, NS, and other records, or the reverse DNS of an IP.

Enter a domain to see its public records, or an IP address to see its reverse DNS. Results come from Cloudflare’s public resolver, so a recent change at your DNS host can take time to appear. Lookups go from your browser to Cloudflare’s public DNS resolver.

Looking up DNS because email isn’t arriving?

Records only show the setup. Our DMARC monitoring shows which services send as your domain and whether their mail passes, and we fix the ones that don’t.
