Verdict scenarios

How DNS Records (MX/NS) shapes the call

Three real-world situations where DNS Records (MX/NS) evidence dominates the decision. Verdict and explanation are how VerdictIQ would frame the outcome to an analyst, not raw signal slugs.

High riskVERDICT · BLOCK
The situation

A domain pointing to disposable mail providers and a free DNS service, with name servers rotating multiple times in a single week.

VerdictIQ explains

“Decline. The mail and DNS plumbing reads as throwaway: free providers, high churn, no commitment. Standard pattern for short-lived attack infrastructure.”

Medium riskVERDICT · REVIEW
The situation

A domain whose MX records point to a credible provider but whose NS set has changed three times in the last 60 days.

VerdictIQ explains

“Send to analyst review. The mail story is fine but the DNS churn suggests reconfiguration; likely benign migration, possibly staging.”

Low riskVERDICT · ALLOW
The situation

A domain on a paid enterprise email provider, with stable name servers held for years across a known DNS operator.

VerdictIQ explains

“Allow. The DNS and mail configuration is paid, stable, and operator-grade. No infrastructure reason to delay.”
