DNS Security & Trust Posture
Risk Level:
Critical Risk
1 protocols configured, 8 not configured
1 action required
2 recommendations
Analysis Confidence
MODERATE
Some DNS data may be stale or incomplete, limiting confidence. Resolver agreement and system maturity are adequate.
Email Spoofing
Vulnerable
Brand Impersonation
Not Set Up
DNS Tampering
Unsigned
Certificate Control
Open
What Requires Attention
Critical
No SPF and no DMARC — domain is completely unprotected against email spoofing. Both protocols are RFC-recommended (not mandatory), but their absence leaves the domain open to impersonation (CVE-2024-7208, CVE-2024-49040)
Recommended
Publish an SPF record to authorize legitimate mail senders
Recommended
Publish a DMARC record starting with p=none and rua reporting
The BIG Questions
Can this domain be impersonated by email?
Yes
no SPF or DMARC protection
Can DNS itself be tampered with?
Possible
DNSSEC is not deployed, DNS responses are not cryptographically verified
Can this brand be convincingly faked?
Yes
No DMARC policy (RFC 7489) — attackers can send email appearing to be from this domain with no sender-authentication barrier
Is mail transport encryption enforced?
No
No MTA-STS or DANE — mail transport encryption is opportunistic only
Is certificate issuance controlled?
No
No CAA records — any certificate authority may issue certificates for this domain
Does this domain publish AI agent instructions?
Yes
llms.txt and llms-full.txt published — AI models receive structured context about this domain
Is AI crawling of our content controlled?
No
robots.txt present but does not block AI crawlers — content may be freely scraped
Has someone manipulated AI recommendations about us?
No
No indicators of AI recommendation manipulation found
Are there hidden AI prompts on our site?
No
No hidden prompt artifacts found in page source

Priority Actions 4 total Achievable: Low Risk
High
Add DMARC Reject for No-Mail Domain
This domain has no MX records and appears to be a website-only domain. A DMARC reject policy tells receiving mail servers to reject any email claiming to be from your domain.
High
Lock Down SPF for No-Mail Domain
This domain has no MX records and appears to be a website-only domain. Publishing a strict SPF record explicitly declares that no servers are authorized to send email, preventing attackers from spoofing your domain.
Medium
Enable DNSSEC
DNSSEC is not enabled for this domain. DNSSEC provides cryptographic authentication of DNS responses, preventing cache poisoning and DNS spoofing attacks.
Low
Add CAA Records
CAA records specify which Certificate Authorities may issue certificates for your domain, reducing the risk of unauthorized certificate issuance.

This domain belongs to AS213891 and hosts critical infrastructure services

<h2>What is b621?</h2>
<p>
B-621 is the designation of the asteroid belonging to the Little Prince in
Antoine de Saint-Exupéry's classic short story, The Little Prince. Just as
the Little Prince's asteroid is home to indispensable elements—a rose,
several volcanoes, and a baobab tree requiring careful tending—our b621
domain name similarly serves as a small yet vital home for the AS213891
network infrastructure.
