Online DNS Lookup

It is the browser version of dig. Enter a domain and record type, and the server performs a real query against public resolvers, returning records, TTL and response time with nothing to install.

A points a domain to an IPv4 address; AAAA to IPv6; CNAME is an alias pointing to another domain; MX specifies mail servers with priority; TXT stores SPF, DKIM and domain-verification text; NS specifies the authoritative name servers for the domain.

TTL (Time To Live) is how long, in seconds, the record may be cached. A lower TTL makes changes take effect sooner but increases query volume.

DNS answers depend on resolver caches, routing and CDN steering. The same domain can return different IPs depending on the recursive resolver, unexpired cache or geolocation; public resolvers may also differ in the response code for a non-existent name.

An apex domain (e.g. example.com) usually cannot have a CNAME; also, recursive resolvers may follow the CNAME when resolving A/AAAA and return the final IP without listing the CNAME separately.

NXDOMAIN means the domain does not exist; "no records" means the domain exists but has no data of the requested type. Some authoritative servers answer with NOERROR + SOA instead of NXDOMAIN, so the returned records are what matter.

Cloudflare and Google are global and fast; Quad9 focuses on security blocking; AliDNS, DNSPod and Volcengine reflect mainland China more closely. Switch between them to compare answers.
