Request Demo

Live DNS Lookup

The Live DNS API allows real-time lookups of DNS resource records such as A, AAAA, MX, NS, CNAME, SOA, TXT, and SPF, and also supports reverse IP lookups using PTR records by specifying the ipAddress parameter. The API uses the type parameter to look up specific DNS records, such as NS, or multiple records separated by commas (e.g., mx,ns). To retrieve all record types, simply set the type parameter to all.

Authorization

You can make authorized requests to our API by passing API key as a query parameter. To get your API key, login to our billing dashboard and get your API key! If your API key has been compromised, you can change it by clicking on reset button in billing dashboard.

Query Parameters

Required

apiKey
Get your API key from our billing dashboard.
domainName
The domainName for requested dns data.
ipAddress
The ipAddress for requested DNS's PTR record. OR You can pass both domainName & ipAddress. At least one is required.
type
Type of DNS record like all/comma separated list (A, AAAA, TXT, NS, MX, SOA, SPF)

Optional
