DNS Lookup

Free online DNS lookup tool. Query A, AAAA, CNAME, MX, TXT, NS, SOA, CAA and PTR records for any domain over encrypted DNS-over-HTTPS with automatic provider fallback.

dns-lookup.run

Queries are sent over encrypted DNS-over-HTTPS to Cloudflare (1.1.1.1), with Google DNS as automatic fallback.

What is a DNS lookup?

A DNS lookup is the process of asking the Domain Name System which IP address (or other record) belongs to a domain name. When you type example.com into a browser, a DNS lookup translates that name into an IP address like 93.184.216.34 so your device knows where to connect.

This tool queries live DNS servers over encrypted DNS-over-HTTPS and supports the nine most useful record types: A (IPv4 address), AAAA (IPv6), CNAME (alias), MX (mail servers), TXT (verification and email security), NS (name servers), SOA (zone authority), CAA (certificate rules) and PTR (reverse DNS).

How to use

  1. 01Enter a domain name, e.g. example.com.
  2. 02Pick the record type: A, AAAA, CNAME, MX, TXT, NS, SOA, CAA or PTR.
  3. 03Click Lookup — the query goes over encrypted DNS-over-HTTPS.
  4. 04Read the records with name, type, TTL and value.

Frequently asked questions

Which DNS server answers my query?
Queries go to Cloudflare's 1.1.1.1 resolver over encrypted DNS-over-HTTPS, with Google Public DNS as an automatic fallback if Cloudflare is unreachable — so the tool keeps working even during provider outages.
What does TTL mean in the results?
TTL (Time To Live) is how many seconds resolvers may cache the record. A TTL of 300 means changes to that record can take up to 5 minutes to propagate to everyone.
Why do I see different results than my own network?
DNS answers can vary by resolver and location (geo-DNS), and your local resolver may serve cached records. This tool shows the current answer from public resolvers.
Is my query private?
The domain you query is sent to the DNS provider (Cloudflare or Google) over an encrypted connection — the same thing that happens when you visit any website. Nothing is stored by this site.
