DNS Lookup

Query DNS records for any domain using Google or Cloudflare.

Perform DNS lookups for any domain using Google or Cloudflare DNS-over-HTTPS. Query A, AAAA, MX, NS, TXT, SOA, SRV, CNAME, CAA, and PTR records to inspect how a domain is configured across the internet.

How to Use the DNS Lookup Tool

Enter a domain name, select the DNS record type and resolver, then click Lookup. Results appear in a table with copy buttons for individual records, plus a raw JSON view.

Type a domain name (e.g., google.com) in the input field.
Choose a record type from the dropdown — A for IPv4, AAAA for IPv6, MX for mail, etc.
Select a DNS server: Google (8.8.8.8) or Cloudflare (1.1.1.1).
Click Lookup and view the results in Table or JSON view.
Copy individual records or all results at once.

The tool supports A, AAAA, CNAME, MX, NS, TXT, SOA, SRV, CAA, and PTR records — covering all common DNS record types used on the internet.
