DNS Lookup
Free DNS lookup tool — query A, AAAA, MX, TXT, NS, CNAME and SOA records for any domain instantly, straight from your browser over DNS-over-HTTPS.
About the DNS Lookup
This free DNS lookup tool queries the public Domain Name System for any domain and shows you the exact records the internet uses to route traffic. Enter a domain, pick a record type — A, AAAA, MX, TXT, NS, CNAME or SOA — and get back every matching record with its TTL and value in a clean table.
Queries run over Cloudflare's DNS-over-HTTPS endpoint (1.1.1.1) directly from your browser, so there is no server in the middle and nothing is logged on our side. Choose "ALL" to fetch the common record types in one go, useful when you are debugging email delivery, verifying a domain, or migrating hosting.
DNS records are the backbone of every website and email service. A records point a domain to an IPv4 address, MX records direct email, TXT records hold SPF and DKIM verification, and NS records name the authoritative servers. Reading them is the fastest way to confirm a change has propagated.
How to Use the DNS Lookup

- 2Choose a record type, or pick ALL to fetch the common types at once.
- 3Click Look up DNS and read the records in the results table.

Frequently Asked Questions
What is a DNS lookup?
A DNS lookup asks the Domain Name System what records a domain has — the IP address it points to, which servers handle its email, and any text records used for verification. It is how browsers and mail servers turn a human-friendly domain like example.com into the numeric addresses machines actually connect to.
Which DNS record types can I check?
This tool queries A (IPv4 address), AAAA (IPv6 address), MX (mail servers), TXT (SPF, DKIM and verification strings), NS (authoritative nameservers), CNAME (aliases) and SOA (zone authority). Select ALL to retrieve the common types in a single query.
Why do my DNS changes not show up yet?
DNS records are cached according to their TTL (time to live), so a change can take anywhere from a few minutes to 48 hours to appear everywhere. This tool queries Cloudflare's resolver live, which usually reflects updates quickly, but other networks may still serve the old cached value until the TTL expires.
Is this DNS lookup private?
The query is sent from your own browser to Cloudflare's public DNS-over-HTTPS resolver — it never touches our servers, so we do not see or store the domains you look up. Cloudflare's 1.1.1.1 resolver has a published privacy policy and does not retain personally identifiable query logs.
What is the difference between A and AAAA records?
An A record maps a domain to an IPv4 address (like 93.184.216.34), while an AAAA record maps it to an IPv6 address (like 2606:2800:220:1:248:1893:25c8:1946). Modern sites often publish both so visitors on either protocol can connect.
