What is DNS Lookup Tool?

The DNS Lookup Tool allows you to easily query and inspect the Domain Name System (DNS) records of any website or domain. It uses Cloudflare's fast DNS-over-HTTPS (DoH) API to securely fetch the latest global DNS propagation data.

How to Use DNS Lookup Tool

1. Enter a valid domain name (e.g., example.com) 2. Select the type of record you want to query (A, AAAA, MX, TXT, etc.) 3. The table will instantly display the resulting records, including TTL and priority (if applicable) 4. Click the 'Copy' button next to any record to copy the target value to your clipboard.

Common Use Cases

Verifying email deliverability setups (SPF, DKIM, DMARC) via TXT records
Checking if website DNS migrations have propagated (A/AAAA/CNAME records)
Inspecting mail server configurations (MX records)
Troubleshooting generic domain configuration issues

Frequently Asked Questions

Which DNS record types are supported?

This tool currently supports querying A (IPv4), AAAA (IPv6), MX (Mail Exchange), TXT (Text), CNAME (Canonical Name), NS (Name Server), SOA (Start of Authority), and PTR (Pointer) records.

Where does the DNS data come from?

We use Cloudflare's 1.1.1.1 DNS over HTTPS (DoH) API, which provides extremely fast and secure queries directly against one of the internet's fastest public resolvers.

What does TTL mean?

TTL stands for Time-To-Live. It is the amount of time (in seconds) that intermediate DNS servers are allowed to cache the record before they need to ask the authoritative server again.
