Live DNS Lookup

Enter a domain to view A, AAAA, CNAME, MX, TXT, NS, SOA, and CAA records, DNSSEC, email security, and registrar info directly on this page.

DNS records will appear here after you run a lookup.

What this tool does

DNS lookups reveal how a domain resolves across the internet, which is essential for troubleshooting and deployment reviews. This tool checks A, AAAA, CNAME, MX, TXT, NS, SOA, and CAA records, verifies DNSSEC and email authentication (SPF/DMARC/DKIM), and pulls registrar details, all in one place.
