DNSSEC records are shown only when returned. An unset AD flag is not proof that a zone is unsigned. MTA-STS, TLS-RPT, BIMI and arbitrary DKIM selectors are not measured here; their absence cannot be inferred.

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.

Changes to amazon.com.au

No entry for this domain appears in the current public change feed. The feed is a selected sample, so this does not establish that its DNS stayed unchanged.

Start monitoring to build a history from your first check, or explore observed changes across the dataset.

SPF diagnostics

Static observations from the published SPF record. No nested include or redirect dependencies were evaluated. The actual sending IP and evaluation path are needed to assess the RFC 7208 limit of 10 DNS-dependent terms.

1DNS-dependent terms — nested dependencies are not checked; headroom is not confirmed

Modern mail security across the dataset

The required DNS labels are not queried. Adoption is unknown for this domain and for the population. Apex TXT anomalies are listed separately in the security posture report.

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.

amazon-smtp.amazon.com

PTR records were observed for all returned addresses of this MX.

DNS attempt: 2026-09-07 05:30:47 UTC. 1 of 1 addresses queried; 1 definite address results in the saved observation.

Observed PTR names are outside this domain. Name relationships are not a forward-confirmed reverse DNS test.

Where amazon.com.au stands

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

Context of .au

Most used sending platforms among 3,520 SPF-publishing domains in Australia: Amazon SES 19.2% · SendGrid (Twilio) 19.1% · Mailchimp 15.5% · Mandrill 14.2%. amazon.com.au runs a stack that is not among the most common in this zone.

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 2 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 amazon.com.au and does not prove that a particular message reaches the inbox or spam folder.
