Instantly query any DNS record type for any domain, A, AAAA, MX, CNAME, TXT, PTR, NS, and SOA, across multiple public resolvers.
Type a domain like example.com, no https:// or trailing paths needed, the tool strips them automatically.
Choose Google, Cloudflare, OpenDNS, Quad9, or Global (queries three resolvers and merges unique results).
Use the chips to check all eight record types at once, or narrow the query to just the ones you care about.
Results are grouped by record type with name, value, TTL, and priority. Toggle chips to filter the view without re-querying.
DNS records are instructions stored in the Domain Name System that control how traffic is routed for a domain. Each record type serves a specific purpose.
Map a domain name to an IPv4 (A) or IPv6 (AAAA) address. The backbone of website hosting and server routing.
Defines which mail servers receive email for the domain. A missing or wrong MX means no email is received.
Stores arbitrary text, used for SPF, DKIM, DMARC, and domain-ownership verification by Google, Microsoft, and others.
Creates an alias that points one domain name to another. Common for subdomains, CDNs, and third-party services.
Maps an IP address back to a domain name (reverse DNS). Critical for mail-server reputation and spam filtering.
NS lists the authoritative nameservers for the zone; SOA carries zone administration details like the serial number and refresh intervals.
SPF, DKIM, and DMARC all live in TXT records. Without them, receiving servers cannot verify your emails are legitimate.
MX records tell the internet which servers accept email for your domain. A wrong MX record means lost mail.
DNS changes do not apply instantly, TTL controls how long resolvers cache. Lower TTL before migrations to speed up rollout.
A DNS record lookup queries the Domain Name System for the records published under a domain, the same query your browser or a mail server would make, and shows you exactly what resolvers around the world see.
Each resolver caches records for the duration of the TTL. After a DNS change, one resolver may still serve the old cached value while another already returns the new one. Comparing resolvers is a quick way to spot in-flight propagation.
Both map a hostname to an IP address: an A record points to an IPv4 address (like 192.0.2.1), while an AAAA record points to an IPv6 address (like 2001:db8::1). Domains commonly publish both.
MX records control where your mail is delivered, TXT records carry SPF, DKIM, and DMARC authentication, and PTR records establish reverse DNS for your sending IPs. Problems in any of them can send your mail to spam.
Just enter the full subdomain (like mail.example.com) in the input. The tool queries whatever hostname you give it, subdomains, apex domains, or deep labels.
