Reverse NS Examples · Example 1 of 2 in Options

Any Name Server Under the Same Domain

GEThttps://api.deepinfo.com/v1/discovery/reverse-ns

With apex=true, any name server under cloudflare.com matches: 52,267,578 domains instead of 123,773.

Param: apex ns
Value: true may.ns.cloudflare.com

apex=true matches every name server whose registrable domain is that of ns, here cloudflare.com.

The total grows from 123,773 to 52,267,578: the domains on any Cloudflare name server. The records shown use other Cloudflare name servers (autumn, charles, alexa, bowen).

In the response, look at result_count and results[].dns.ns.name_servers.
