# Look up DNS records

> Resolves one record type, or with no `type` the everyday set (A, AAAA, CNAME, MX, NS, TXT, SOA, CAA). A type with no records comes back empty rather than as an error; 404 only when every type is empty. IP addresses are refused — pass a domain. Limited to 30 requests per minute per IP.
