DNS Lookup Tool
Resolve A, AAAA, MX, TXT, CNAME records
Free online DNS lookup — resolve A, AAAA, MX, TXT, CNAME and NS records for any domain. Choose from multiple resolvers (Google, Cloudflare, Quad9). Terminal-style output — essential for debugging email delivery, DKIM and domain migrations.
// quick guide
DNS (Domain Name System) lookup queries nameservers to resolve domain names to IP addresses and other metadata records. It is an essential diagnostics tool for webmasters, developers, and sysadmins to verify domain configurations, email delivery settings, and propagation status.
How to use this tool:
- Enter the domain name (e.g.
example.com) you want to query. - Select the DNS record type: A (IPv4 address), AAAA (IPv6 address), MX (Mail Exchanger), TXT (Text annotations for SPF/DKIM), CNAME (Canonical name), or NS (Name servers).
- Choose your preferred resolver: Cloudflare, Google DNS, or Quad9.
- Analyze the resolved records displayed in a dense terminal-style table output.
// frequently asked questions
What are the common DNS record types?
<strong>A:</strong> Maps a domain to an IPv4 address. <strong>AAAA:</strong> Maps a domain to an IPv6 address. <strong>MX:</strong> Directs emails to a mail server. <strong>TXT:</strong> Holds text information, commonly used for SPF, DKIM, and site verification. <strong>CNAME:</strong> Aliases one domain to another.
Why does my new DNS record not show up?
DNS records are cached by ISP servers and routers based on a Time-To-Live (TTL) setting. When you update a record, it can take up to 24–48 hours to propagate globally, though choosing different public resolvers in the tool can help check if they have updated.
What are Cloudflare, Google DNS, and Quad9 resolvers?
They are public DNS resolvers. Using different resolvers lets you test if your domain updates have propagated across different global networks (Google at 8.8.8.8, Cloudflare at 1.1.1.1, and Quad9 at 9.9.9.9).
