DNS Lookup
Query DNS records for any domain using Cloudflare's public DNS.
Understanding DNS Records
DNS is the internet's phone book — it translates human-readable domain names into machine-readable IP addresses. Different record types serve different purposes:
- A — maps a domain to an IPv4 address (e.g., 104.21.29.235)
- AAAA — maps a domain to an IPv6 address
- CNAME — creates an alias pointing to another domain
- MX — specifies mail servers for receiving email
- TXT — stores text data, often for domain verification (SPF, DKIM, DMARC)
- NS — specifies the authoritative name servers for the domain
This tool queries Cloudflare's public DNS resolver (1.1.1.1) using the DNS-over-HTTPS protocol for privacy. For domain registration details, use our WHOIS Lookup. To check for DNS leaks, try the DNS Leak Test.
FAQ
What are DNS records?
DNS records map domain names to IP addresses and other data. A records point to IPv4 addresses, AAAA to IPv6, MX to mail servers, CNAME to aliases, TXT to text data (often for verification), and NS to authoritative name servers.
What is TTL?
TTL (Time To Live) tells DNS resolvers how long to cache a record, in seconds. Lower TTL means faster DNS propagation but more queries to the authoritative server.
