Query any DNS record type for a domain and see raw answers instantly.
Queries are resolved via Google's public DNS-over-HTTPS resolver, run live from your browser.
DNS Lookup / Checker queries any of the common DNS record types — A, AAAA, CNAME, MX, TXT, NS or SOA — for a domain and shows you the raw, authoritative answer straight from the DNS. It's the same information your operating system's own resolver uses, surfaced in a clean readable table instead of a terminal command.
The tool sends your query to Google's public DNS-over-HTTPS endpoint, a resolver that supports fast, encrypted, CORS-friendly lookups directly from a web page — something a traditional DNS query over UDP port 53 cannot do inside a browser. The resolver returns each matching record along with its TTL (time-to-live, in seconds), which tells you how long that answer is cached before resolvers will re-check it.
An A record maps a domain to an IPv4 address; AAAA does the same for IPv6. A CNAME record points one hostname to another canonical name instead of an IP. MX records list the mail servers responsible for handling email for the domain, each with a priority value. TXT records hold arbitrary text and are commonly used for domain verification, SPF, DKIM and DMARC email authentication policies. NS records list the authoritative name servers for the zone. SOA (Start of Authority) holds administrative metadata about the zone itself, including the primary name server and refresh timers.
Developers use this to confirm a DNS change has propagated after updating a record. Email administrators use it to verify MX, SPF and DKIM TXT records are configured correctly before sending campaigns. Support teams use it to quickly diagnose "why isn't my site loading" tickets by checking whether A/AAAA records actually point where they should.
Not every domain configures every record type — for example, many domains have no AAAA record if they don't support IPv6, and a subdomain used only for a CNAME won't have its own A record.
It reflects what the resolver currently has cached or has just fetched from the authoritative name servers — usually accurate within the TTL window shown for each record.
DNS changes propagate based on the TTL of the previous record — resolvers around the world won't refresh until their cached copy expires, which can take minutes to 48 hours depending on configuration.
Yes, enter the full subdomain, e.g. mail.example.com, and select the record type you want to inspect.
WHOIS/RDAP shows registration ownership data; DNS lookup shows the actual technical records that route traffic and email for the domain.
