About DNS Lookup
This tool queries any DNS record type for any domain — equivalent to running nslookup or dig from your terminal, but in your browser. Results are fetched via Cloudflare DNS-over-HTTPS (1.1.1.1) for fast, accurate, privacy-respecting queries with no third-party visibility into your lookups.
Each record type serves a different purpose: A maps a domain to an IPv4 address; AAAA to an IPv6 address; MX specifies mail servers with priority; NS lists authoritative name servers; TXT holds SPF, DKIM, DMARC, and domain verification strings; CNAME creates an alias from one name to another; SOA shows the authoritative server and zone serial; CAA restricts which certificate authorities can issue SSL certificates for the domain.
The TTL column shows how long resolvers cache each record in seconds — a TTL of 300 s means changes propagate in 5 minutes; 86400 s means up to 24 hours. Results per type are cached in the browser so switching tabs is instant. To find the hostname behind an IP discovered here, use Reverse DNS Lookup. To test reachability after finding an IP, run a Ping Test.
