What Is the DNS Lookup Tool?
The DNS Lookup Tool lets you query the Domain Name System for any domain and view all associated records in one place. Enter a domain name and instantly see its A, AAAA, CNAME, MX, TXT, NS, and SOA records, complete with TTL values and structured data. The tool uses Cloudflare's DNS-over-HTTPS resolver for fast, reliable results and runs entirely in your browser — no data is sent to our servers.
DNS records are the backbone of the internet. They tell browsers where to find websites (A/AAAA records), where to send email (MX records), which nameservers control a domain (NS records), and store verification and security data (TXT records). Whether you're debugging a DNS issue, verifying domain configuration, or researching a domain's infrastructure, this tool gives you everything you need.
How to Look Up DNS Records
Type or paste a domain name into the input field and click Lookup (or press Enter). The tool queries all major record types simultaneously and displays results in organized, collapsible sections. Each record shows its name, TTL, and value in an easy-to-read table format. A summary card at the top gives you an instant overview: the domain's IP address, nameservers, and counts for mail and TXT records.
You can export all records as CSV for spreadsheets, JSON for programmatic use, or copy the full results to your clipboard. Use the quick-access buttons to look up popular domains and see what well-configured DNS records look like. The tool strips URL prefixes automatically, so you can paste a full URL and it will extract the domain for you.
Frequently Asked Questions
What is a DNS lookup?
A DNS lookup queries the Domain Name System to find records associated with a domain name. It translates human-readable domain names (like example.com) into IP addresses and retrieves mail server, nameserver, and other configuration records.
What are the different DNS record types?
A records map domains to IPv4 addresses. AAAA records map to IPv6. CNAME records are aliases pointing to another domain. MX records specify mail servers. TXT records hold text data like SPF and DKIM. NS records identify authoritative nameservers. SOA records contain zone administration info.
Why do some domains have no AAAA or CNAME records?
Not all domains use IPv6 (AAAA records). CNAME records are only used when a domain is an alias for another domain — root domains typically use A records instead. The absence of these records is completely normal.
How long does DNS propagation take?
DNS changes can take anywhere from a few minutes to 48 hours to propagate globally. TTL (Time To Live) values on records control how long resolvers cache results. Lower TTL values mean faster propagation but more DNS queries.
Is this tool accurate?
This tool queries Cloudflare's DNS-over-HTTPS resolver (1.1.1.1), one of the fastest and most reliable public DNS services. Results reflect what Cloudflare's resolver currently returns, which may differ slightly from other resolvers during propagation.
