DNS Lookup

Check A, AAAA, MX, TXT, NS, CNAME, SOA and CAA records for any domain — instant, from Cloudflare + Google DNS

Domain name

Record type

A, AAAA, MX, TXT, NS and CNAME in practice

A/AAAA map names to IPv4/IPv6; MX lists mail servers by priority; TXT carries SPF/DKIM blobs.
CNAME is an alias that cannot coexist with other records at the same name — a classic misconfiguration.
TTL values tell resolvers how long to cache — lower it BEFORE migrating DNS.

What Is a DNS Lookup?

The Domain Name System translates a domain name into the addresses and records behind it: A and AAAA records point to servers, MX records route email, TXT records carry SPF and DKIM verification, and CNAME, NS, SOA and CAA records describe aliases, authority and certificate rules. When a site loads slowly, email lands in spam or a domain stops working, the answer often lives in its DNS records. This lookup resolves all eight record types at once over DNS-over-HTTPS, showing each record with its TTL, so you can see exactly what the internet is currently being told about a domain.

What the lookup returns

🔎 A, AAAA, CNAME, MX, TXT, NS, SOA and CAA records in one query, or a single type
⚡ Queries Cloudflare's DNS-over-HTTPS with automatic Google fallback
⏱️ TTL shown for every record
📋 One-click copy of any record value
🧭 Accepts a bare domain, a full URL, or an IP address

When you would look a domain up

Verifying DNS has propagated before a site launch
Confirming SPF, DKIM and DMARC TXT records after setting up email
Debugging MX records when mail bounces
Auditing CAA records before issuing an SSL certificate

Unlike the text tools on this site, a DNS lookup cannot run locally — the domain you type is sent to our server, which queries Cloudflare and Google's public resolvers over DNS-over-HTTPS. That is inherent to DNS itself; no account or API key is needed, and queries are cached for two minutes.

Every record type answers a different question

🔒

Eight record types at once

A, AAAA, CNAME, MX, TXT, NS, SOA, and CAA records resolve together over DNS-over-HTTPS, with the ALL option returning every type for the domain in one pass.

⚡

TTL and copy on every record

Each answer displays its TTL, and a one-click copy button per record puts the raw value on your clipboard, for dig-style workflows or configuration files.

📊

Cloudflare with Google fallback

Queries go through the Cloudflare DoH endpoint and switch to Google when the first resolver stumbles, so a single provider outage never blanks the results.

How it works

1
Type a domain and pick a record type (or All).
2
We resolve it over DNS-over-HTTPS from Cloudflare, falling back to Google.
3
Read the records with their TTLs and copy any value with one tap.

Frequently asked questions

What is a DNS lookup used for?

To see the DNS records behind a domain: which servers host its website (A/AAAA), where its email goes (MX), verification and SPF/DKIM strings (TXT), its nameservers (NS), aliases (CNAME) and certificate authorization (CAA). It's essential for diagnosing website/email problems and verifying DNS changes.

How fresh are the results?

We query live DNS-over-HTTPS resolvers (Cloudflare, then Google) and cache each answer for only 2 minutes. Note that DNS changes propagate gradually worldwide — a record you just changed may still show the old value until its previous TTL expires.

Why do A and CNAME both show up?

When a name is a CNAME (alias), resolvers return the CNAME plus the final A/AAAA it points to. We show the whole chain so you can see exactly how the name resolves.
