DNS Lookup
Scan a domain's A, AAAA, MX, TXT, NS & more.
Queries run from your browser via Google's secure DNS-over-HTTPS resolver. Results reflect that resolver's current view and may differ during propagation.
Reading DNS records
DNS records tell the internet how to reach a domain and its services. This scanner checks the most useful ones in one go:
- A / AAAA — the IPv4 / IPv6 addresses the domain points to.
- CNAME — an alias pointing to another domain.
- MX — mail servers that receive email for the domain.
- TXT — free-form records, often SPF/DKIM/DMARC and domain verification.
- NS — the authoritative nameservers.
- SOA — the zone's start-of-authority metadata.
- CAA — which certificate authorities may issue SSL certs.
Queries use secure DNS-over-HTTPS and run entirely in your browser. Because DNS is cached around the world, results can differ briefly after you change records (propagation).
