Reverse MX Examples · Example 1 of 1 in Ordering

Earliest Expiry First

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

The domains on Cloudflare Email Routing, the earliest WHOIS expiry date first (ordering=domain.whois.expiry_date).

Param: ordering mx
Value: domain.whois.expiry_date route1.mx.cloudflare.net

ordering=domain.whois.expiry_date sorts by the expiry date in the WHOIS record, earliest first.

The first records have expiry dates long in the past (pub.pw on August 26, 2016, vb.lk and byte.lk in 2018): their WHOIS record shows an expiry date that has passed, while their MX record still points to Cloudflare. Sorting on a date field is a quick way to find such stale records.

In the response, look at results[].domain.whois.expiry_date.
