Recorded DNS history

Registry presence: first seen 2026-04-28; last seen 2026-09-07. These are appearances in our domain registry, not domain registration dates or earlier DNS values.

This history starts with saved RR captures. Provider market-share charts are aggregate context, not this domain’s DNS history. Dates identify observations; no continuous validity between them is implied. Equivalent RR states are combined, ignoring response TTL and capture-time changes. Up to 30 distinct RR states and 60 dated captures are retained within a per-domain byte limit.

No earlier different RR snapshot is available for comparison.

Reverse DNS of inbound MX hosts

These are separately dated observations of inbound MX addresses. They do not identify the actual sending IP. To assess outbound mail, check current forward and reverse DNS of the actual sending IP; FCrDNS and delivery were not measured here.

Where opinary.com stands

The same snapshot cut by zone, by list position and by how alive the published policies are.

How to interpret these observations

MX identifies the observed inbound mailbox or gateway. SPF includes identify services authorised to send for the domain. DMARC shows the published authentication policy. The dataset currently contains 3 populated signal groups for this page.

Observed deliverability context: based on the available observations, this page describes DNS configuration only. It does not represent a complete audit of opinary.com and does not prove that a particular message reaches the inbox or spam folder.
