Look up A, AAAA, CNAME, MX, TXT, NS, SOA, CAA, and SRV records for any domain. Free online dig / nslookup replacement, browser-based, no signup.
DNS (Domain Name System) is the address book of the internet — it translates the domain names humans type (tooloogle.com) into the IP addresses computers use (104.21.x.x). A DNS lookup is the act of asking a DNS server: "What records do you have for this domain?"
This tool is a browser-based replacement for the classic dig and nslookup command-line utilities. You don't need a terminal — type a domain, pick a record type, and see the live results.
Enter any domain (with or without www.). Choose a record type from the dropdown — or select All to fetch every common record at once. The tool queries Google's public DNS-over-HTTPS endpoint, which gives you the same authoritative answer that dig @8.8.8.8 would return. Results appear in a copy-friendly table with TTL, record value, and (where useful) a short plain-English explanation.
A — the IPv4 address(es) the domain points to.
AAAA — the IPv6 address(es) the domain points to.
CNAME — an alias for another domain (e.g. www.example.com aliased to example.com).
MX — mail-exchange servers; the addresses that receive email for the domain, with priorities.
TXT — free-form text records used for SPF, DKIM, DMARC, Google/Microsoft domain verification, and BIMI.
NS — authoritative nameservers for the domain.
SOA — start-of-authority record with serial number, refresh, retry, expire, and minimum TTL.
CAA — certificate-authority authorization; which CAs are allowed to issue TLS certs for this domain.
SRV — service location records (used by SIP, XMPP, Minecraft, Matrix, and other protocols).
PTR — reverse-DNS, mapping an IP back to a hostname.
Queries Google's public DNS-over-HTTPS resolver — fast, anonymous, no rate-limit surprises
"All records" mode fetches every common type in parallel
Shows TTL alongside each record (so you know how long it's cached)
Auto-strips http://, https://, and paths — paste a URL and it just works
Highlights special TXT records: SPF, DKIM, DMARC, Google verification
One-click copy for any record value
Dark mode that follows your system preference
Type or paste a domain into the input (URLs and bare domains both work).
Select a record type (or leave on All for a full snapshot).
Click Lookup.
Results appear in a table with record value, TTL, and copy buttons.
Real-world workflows where this tool saves time:
Email deliverability — verify SPF, DKIM, DMARC, and MX records when setting up SendGrid, Mailgun, Google Workspace, or Microsoft 365.
Domain migration — check whether new nameservers and A-records have propagated globally.
SSL / certificate issuance — check CAA records before Let's Encrypt or a commercial CA tries to issue.
Debugging — figure out why a site won't load, why email is bouncing, or why a subdomain isn't routing correctly.
Security audits — inspect TXT records for leaked verification tokens or stale configurations.
Domain reconnaissance — look up nameservers, mail exchangers, and SPF includes for a competitor or vendor.
Learning DNS — students and new engineers can see how every record type is structured.
The tool uses Google's public DNS-over-HTTPS (dns.google/resolve), which is anonymous and doesn't log queries to your Google account. Your lookup history stays in your browser tab.
Responses match what authoritative dig queries return — no proprietary caching layer, no "enriched" data, no obfuscated TTLs. What you see is what your applications will see.
Sub-second responses, no signup, no rate limits, no ads in your data. Open the tool, type, look up.
An A record holds an IPv4 address (104.21.45.67). An AAAA record holds an IPv6 address (2606:4700::6810:2d43). Modern domains typically have both so they're reachable over either protocol.
dig sometimes show different results than this tool?DNS results are cached — each server respects the TTL set by the authoritative nameserver. If you've just changed a record, different resolvers may show old or new values until the TTL expires. This tool queries Google's public resolver, which is usually within seconds of authoritative; for live verification, also query with dig @1.1.1.1 (Cloudflare) and dig @your-isp-resolver to compare.
All three are TXT records that fight email spoofing. SPF lists which servers are allowed to send mail "from" your domain. DKIM is a cryptographic signature attached to outgoing mail. DMARC tells receiving servers what to do if SPF or DKIM fail (reject, quarantine, or just report). Configuring all three correctly is essential for inbox delivery and brand protection.
Time-To-Live, in seconds. The TTL tells caching resolvers how long they may reuse a record before re-querying. A TTL of 300 = 5 minutes; 3600 = 1 hour; 86400 = 1 day. Lower TTLs make DNS changes propagate faster but increase load on the authoritative server.
Yes — use the PTR record type and enter the IP. The tool handles the in-addr.arpa reversal automatically.
Those numbers are priorities. Lower = higher priority. Mail servers try the lowest-priority MX first and fall back to higher numbers if it's unreachable. Equal priorities are load-balanced randomly.
No — DNS lookup requires a network call to query Google's DoH endpoint. The page itself loads once and runs in the browser, but each lookup makes a single HTTPS request.
