DNS Lookup

Overview

This DNS lookup tool queries DNS records for any domain straight from your browser using DNS-over-HTTPS. Pick a record type — A, AAAA, MX, TXT, NS, CNAME, SOA, or CAA — and a resolver (Cloudflare or Google), and the matching records are shown with their TTL and values. The domain you look up does leave your device — that is how DNS is answered — but it goes to the resolver you picked, over HTTPS, and never through a server of ours. It's a fast alternative to command-line dig for verifying DNS changes, mail configuration, and domain records.

Verifying DNS changes propagatedCheck A or CNAME records against both resolvers after updating your DNS to confirm the new values are live.
Debugging email deliverabilityInspect MX and TXT (SPF/DKIM/DMARC) records to make sure your mail configuration is correct.
Auditing a domain's setupReview NS, SOA, and CAA records to understand who runs a domain's DNS and which authorities can issue its certificates.

How it works

Enter a domain

Type a domain name like example.com and pick the record type you want to see.

Pick a resolver

Choose Cloudflare or Google. Your browser sends the query directly to that resolver over HTTPS.

Read the records

Matching records appear in a table with their type, TTL, and value. Switch types to explore mail, text, and nameserver records.

Frequently asked

Does this send my query to your server?

No. The lookup runs in your browser and goes directly to the DNS-over-HTTPS resolver you choose (Cloudflare or Google). We never see the domains you look up.

What does NXDOMAIN mean?

NXDOMAIN means the domain does not exist in DNS. Double-check the spelling — a typo is the most common cause.

Why do I see different results from different resolvers?

Resolvers cache records for their TTL, so one may still be serving an older answer after a change. Comparing Cloudflare and Google can reveal propagation differences.
