Reverse NS Examples · Example 1 of 2 in Lookups

Domains Using One Name Server

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

The domains whose NS record names may.ns.cloudflare.com: 123,773 on the day of capture.

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

Asks for the domains delegated to may.ns.cloudflare.com.

The API found 123,773 domains. Cloudflare gives every zone two of its name servers, so each record lists may next to a second one (vasilii, ray, lex).

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