Associated Domain Finder Examples · Example 10 of 11 in One Association Type

Same Mail Servers (DNS MX)

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

The domains that use the same mail servers as cloudflare.com (Cloudflare Email Security): 1,376.

Param: association domain
Value: dns_mx cloudflare.com

association=dns_mx compares the mail servers of the DNS MX record.

The API found 1,376 domains on mxa and mxb.global.inbound.cf-emailsecurity.net, the inbound servers of Cloudflare’s e-mail security service. Here the association finds a shared service, not a shared owner.

In the response, look at results[].dns.mx.mail_servers.
