DNS Lookup Online
Google DNS checker and online DNS lookup: A, AAAA, MX, TXT, NS and CNAME records for any domain. Fast, free tool.
Google DNS checker and online DNS lookup: A, AAAA, MX, TXT, NS and CNAME records for any domain. Fast, free tool.
Free, instant DNS record lookup for any domain in your browser — no sign-up required.
Use it to check A/AAAA (IP), MX (mail), TXT (SPF/DKIM), CNAME, NS and TTL before pointing a domain or troubleshooting propagation.
Results are presented in a clear, organized way, making analysis easy for both administrators and networking beginners.
Each record type serves a specific role in the DNS zone. Use this table when interpreting lookup results.
| Term | Meaning |
|---|---|
| A | Maps the domain to an IPv4 address (e.g. 192.0.2.10). |
| AAAA | Maps the domain to IPv6 — common on dual-stack sites. |
| CNAME | Alias to another hostname (CDN, www → apex, SaaS). |
| MX | Mail servers for the domain, with numeric priority. |
| TXT | Free-form text: SPF, DKIM, DMARC, ownership verification. |
| NS | Authoritative nameservers — should match your DNS panel. |
| TTL | Cache time in seconds; lower before migrations. |
Quick lookups for well-known domains:
It is the query that translates a domain name into technical information such as the server's IP address, mail servers (MX) and other records configured in the DNS zone.
You can query A and AAAA records (IPv4 and IPv6 addresses), MX (email), TXT (including SPF, DKIM and DMARC), NS (name servers), CNAME (aliases) and more.
The MX (Mail Exchange) record specifies which servers are responsible for receiving a domain's email. It is essential for diagnosing message delivery issues.
DNS changes take time to propagate because of TTL (cache time). Full propagation can take from a few minutes to 48 hours depending on the configuration.
They are TXT records used to authenticate email and prevent spoofing. They help improve deliverability and protect the domain against spam and phishing.
A points to a fixed IP. CNAME points to another hostname. Use CNAME with CDNs and SaaS; use A when the target is a known IP. Apex (@) usually cannot use CNAME.
No. DNS lookup shows technical records (IP, mail, subdomains). WHOIS shows registration data (registrar, expiry, nameservers).
Enter the domain and query A/AAAA and MX records. The tool works as a google dns checker to verify propagation, TTL and records before pointing the domain.
