Associated Domain Finder Examples · Example 8 of 11 in One Association Type

Same IP Address (DNS A)

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

The domains that resolve to the same IP address as apple.com: 64.

Param: association domain
Value: dns_a apple.com

association=dns_a compares the addresses of the DNS A record.

The API found 64 domains that share an address with apple.com (17.253.144.10 in the records shown): applecomputer.co.kr, and also names such as receive-xi.yachts whose A record points to the same address. An IP match finds domains that the registrant data does not.

In the response, look at results[].dns.a.ip_addresses.
