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

Technical Findings

Email Authentication
Can this domain be impersonated by email? Yes — no SPF or DMARC protection
SPF (Sender Policy) Missing
DMARC (Policy) Missing
DKIM (Signatures) Not Detected
Mail Posture Unprotected
Mail Transport Security
Is mail transport encryption enforced? No — No MTA-STS or DANE — mail transport encryption is opportunistic only
MTA-STS Partial
DANE / TLSA Hosted Provider No MX records available — DANE check skipped
TLS-RPT (Reporting) Not Configured
Mail Transport Not Enforced Policy-assessed
DNS Security
Can DNS itself be tampered with? Possible — DNSSEC is not deployed, DNS responses are not cryptographically verified
DNSSEC Partial
DNSSEC not configured - DNS responses are unsigned
NS Delegation Healthy Enterprise DNS (Dedicated Infrastructure)
Delegation Consistency 4 Issues
NS Fleet Health 3 Issues Diversity: Poor
Brand & Certificate Controls
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 certificate issuance controlled? No — No CAA records — any certificate authority may issue certificates for this domain
BIMI (Brand Logo) Not Configured
CAA (Certificate) Open Any certificate authority may issue certificates
AI Surface Scanner Governance Active
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
LLM Context File llms.txt Found Domain provides structured context for AI models Extended
AI Crawler Governance Not Blocking No AI crawler restrictions found in robots.txt
Poisoning Indicators None Found No AI recommendation poisoning indicators detected
Hidden Prompt Artifacts None Found No hidden prompt artifacts detected
Public Exposure Clear No secrets detected in publicly accessible 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
      such as DNS resolution, configuration, logging, and device deployment.

    <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.
