How to use the DNS lookup tool

  1. 1
    Enter a domain name

    Type the domain you want to inspect, for example example.com. You can paste a full URL — the tool strips the http://, paths and trailing dot automatically.

  2. 2
    Pick a record type

    Choose All to see everything at once, or a single type: A for IPv4 addresses, AAAA for IPv6, MX for mail servers, TXT for verification records, CNAME for aliases or NS for name servers.

  3. 3
    Read the results table

    Each record shows its full name, TTL (how long resolvers cache it, in seconds) and its value. Missing records are reported plainly instead of failing silently.

  4. 4
    Copy what you need

    Hit the Copy button on any row to grab the record value for your DNS settings, email configuration or troubleshooting notes.

Features

Six record types

Query A, AAAA, MX, TXT, CNAME and NS records — individually or all at once in a single lookup.

Live public-DNS answers

Every lookup runs against Google's public DNS-over-HTTPS resolver, so you see real, current answers — the same ones the web uses.

Query time shown

Each lookup reports how many milliseconds the resolver took to answer, so you can spot slow or failing DNS.

One-click copy

Every record row carries its own Copy button, ready to paste into your DNS host panel, ticket or email setup guide.

Clear error messages

Nonexistent domains (NXDOMAIN), empty record sets and server failures each get a plain-English explanation instead of a blank page.

TTL in every row

See how long each record stays cached (in seconds) — useful when you are waiting for a DNS change to propagate.

Frequently asked questions

What is a DNS lookup?
A DNS lookup asks the Domain Name System for the records attached to a domain. Those records decide which IP address a domain points to (A and AAAA), where its email is delivered (MX), which servers are authoritative for it (NS), and which verification strings it publishes (TXT).
Where do the results come from?
Lookups go directly from your browser to Google's public DNS resolver (dns.google) over encrypted HTTPS. The answers you see are live and current — the same answers web browsers and mail servers receive.
Why does a domain show "No MX records found"?
Not every domain handles email. If a domain has no MX records, mail servers will try its A record as a fallback, and many domains simply do not accept mail at all. It is normal for parked or brand-protection domains.
What does NXDOMAIN mean?
NXDOMAIN means the domain name does not exist in DNS. The name is either unregistered, misspelled, or so new that no name servers answer for it yet.
What is TTL, and why is it shown?
TTL (time to live) is how many seconds DNS resolvers cache a record before asking again. A low TTL means changes propagate fast; a high one means visitors may see old records for hours after you edit them.
Why do A records show different IPs than my host's panel?
Many sites use CDNs, load balancers or round-robin DNS, so the resolver can return several IPs or different IPs on each query. That is normal — it does not mean your records are wrong.
Is this tool free? Do my queries get stored?
Yes, free and unlimited with no signup. The page does not store, log or share your queries — each lookup is a direct request from your browser to Google's resolver.
