DNS Lookup Tool
Query the live DNS records for any domain — A, AAAA, MX, TXT, NS, CNAME, SOA, CAA and PTR — using DNS over HTTPS, straight from your browser.
What a DNS lookup does
The Domain Name System is the internet's address book: it translates human-friendly names like example.com into the numeric IP addresses machines actually use, and stores other useful records about a domain along the way. A DNS lookup asks a resolver "what records do you have for this name?" and returns the answer. This tool does exactly that using DNS over HTTPS (DoH) against Google's public resolver at dns.google, which replies in JSON — so no server of ours is involved. New to the topic? Start with what is DNS.
Pick a record type to see different facets of a domain:
- A / AAAA — the IPv4 and IPv6 addresses the name points to.
- MX — the mail servers that receive email for the domain.
- NS — the authoritative nameservers responsible for the zone.
- TXT — free-form text used for SPF, domain verification and more.
- CNAME — an alias pointing one name at another.
- SOA / CAA / PTR — zone metadata, certificate-authority rules and reverse pointers.
Every lookup is sent from your browser to Google's public DoH endpoint over HTTPS. That means you see the resolver's view of the world — independent of your own device's DNS settings and any local caching — which is exactly what makes it useful for verifying records. The domain names you check are visible to that resolver, as with any DNS query.
Because it bypasses your local cache, this tool is great for confirming a DNS change has propagated, checking where a domain's mail is handled, or auditing a site's records. To focus on mail servers specifically, use the MX Record Lookup; to turn an IP back into a hostname, use the Reverse DNS Lookup.
Frequently asked questions
What is DNS over HTTPS?
DNS over HTTPS (DoH) lets a browser resolve DNS records over an ordinary encrypted HTTPS request instead of the traditional UDP protocol. This tool uses Google's public DoH endpoint at dns.google, which returns records as JSON — so the whole lookup runs in your browser without a server on our side.
Which record types can I look up?
You can query A, AAAA, MX, TXT, NS, CNAME, SOA, CAA and PTR records. A and AAAA map a name to IPv4 and IPv6 addresses, MX lists mail servers, NS lists nameservers, TXT holds verification and policy strings, and CNAME is an alias to another name.
Why does a domain return no records?
An empty result usually means the domain has no record of that type — for example, many domains have no CAA or no AAAA record. If the domain itself does not exist you will see an NXDOMAIN message instead. Try a different record type to confirm the domain resolves at all.
Is the result affected by my own DNS settings?
No. Because the query goes to Google's public resolver over HTTPS, you see what that resolver sees, independent of the DNS server your device is configured to use. That makes it handy for checking records without local caching getting in the way.
