From observation to a useful check
- What was observed
- The DNS records and classifications in this snapshot.
- What it means
- MX describes inbound mail; SPF authorizes senders.
- What is unknown
- The actual sending IP, nested SPF dependencies, inbox placement and commercial relationships. MTA-STS, TLS-RPT and BIMI adoption are not measured.
- Next check
- Verify current DNS and test a real message: run an inbox placement test.

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 inpi.gov.br
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.
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.
inpi-gov-br.mail.protection.outlook.com
Partial observation: some addresses were not checked or the resolver could not determine their PTR records.
DNS attempt: 2026-09-08 08:28:19 UTC. 3 of 8 addresses queried; 3 definite address results in the saved observation.
