DNS Lookup

Look up A, AAAA, MX, TXT and NS records for any domain, straight from your browser. Fast, raw answers with TTLs.

Live

Look up DNS records

Enter a domain and pick a record type. The query runs live against a public DNS-over-HTTPS resolver.

How this DNS lookup works

Every time you visit a website, your device first asks the domain name system to translate a human name like example.com into a machine address. This tool makes that same request on demand. It sends a DNS-over-HTTPS query to a public resolver and prints the answer exactly as it comes back — record type, value and the TTL (time to live) that tells caches how long to keep it. Because the lookup runs in your browser, your search never touches our servers.

How to read the results

Record What it tells you
AIPv4 address the name resolves to.
AAAAIPv6 address — useful for checking IPv6 readiness.
MXMail servers, with a priority number (lower is preferred).
TXTText records: SPF, DKIM, domain verification and more.
NSAuthoritative nameservers responsible for the zone.

A high TTL means a record is cached for a long time, so changes take a while to appear everywhere. If a value looks wrong right after an edit, it is usually a caching delay rather than a real error — confirm with the propagation checker.

Frequently asked questions

What is a DNS lookup?

A DNS lookup asks the domain name system which records a name has — for example the A record that maps example.com to an IPv4 address. This tool queries a public DNS-over-HTTPS resolver from your browser and shows the raw answer.

What do A, AAAA, MX, TXT and NS records mean?

A points a name to an IPv4 address, AAAA to an IPv6 address, MX lists the mail servers for a domain, TXT holds free-form text (often SPF, DKIM or verification strings), and NS names the authoritative nameservers for the zone.

Why are my results different from another tool?

Different resolvers cache records for different lengths of time (the TTL), and recent changes may not have propagated everywhere. If a record looks stale, check it again after the TTL expires or use the propagation checker.

Is this lookup done from my computer?

Yes. The query runs in your browser against Google's public DNS-over-HTTPS endpoint, so no record passes through our servers. The resolver you query may sit in a different location than you, which can affect geo-based answers.

Records look right, connection still feels wrong?

DNS is only one layer. If pages load slowly or calls drop even though the records resolve, run the full check-up — it tests speed, latency, jitter and DNS together, then tells you what to fix.
