Including Subdomains

GEThttps://api.deepinfo.com/v1/discovery/associated-domain-finder

Adds subdomains to the name-server association of paypal.com: 268 records instead of 238, such as xoom.remitgateway.com.

Param: include_subdomains ordering association domain
Value: true -punycode dns_ns paypal.com

By default the API returns registrable domains only (type: 1). include_subdomains=true adds subdomains (type: 2) that match.

With association=dns_ns, the total grows from 238 to 268: 30 subdomains match as well. This example sorts by name in reverse (ordering=-punycode), which brings subdomains to the top: the records shown are xoom.remitgateway.com (type: 2), xoom.com (type: 1) and www.missionfish.org (type: 2). A subdomain has a subdomain object for its label, and domain holds its registrable domain.

In the response, look at result_count, results[].type, results[].subdomain and results[].domain.punycode.
