Look up DNS records for any domain. Check A, AAAA, MX, TXT, NS, SOA, and CNAME records instantly. Free DNS record checker powered by Cloudflare.
A DNS lookup tool resolves domain names to IP addresses and retrieves DNS records. It queries authoritative nameservers to find A records (IPv4), AAAA records (IPv6), MX records (mail servers), TXT records (SPF, DKIM, DMARC), NS records (nameservers), and more.
Enter any domain name and select the record type you want to check. Results appear instantly showing the record values, TTL (time to live), and the responding nameserver. You can check multiple record types for the same domain.
A DNS lookup translates a domain name (like example.com) into its associated IP address and other DNS records. It queries the Domain Name System, which acts as the internet's phonebook.
DNS changes typically propagate within 24-48 hours, though many changes take effect within minutes. The propagation time depends on the TTL (Time To Live) value set on the records.
The most common types are: A (IPv4 address), AAAA (IPv6 address), MX (mail server), CNAME (alias), TXT (text data like SPF/DKIM), NS (nameserver), and SOA (start of authority).
