DNS check

A single DNS record change can take down your website or email. StrixMonitor instantly detects unexpected changes.

What we monitor

• A / AAAA records — IP address of the domain
• MX records — email delivery routing
• CNAME records — domain aliases and redirects
• TXT records — SPF, DKIM, ownership verification
• NS records — authoritative nameservers

How it works

StrixMonitor saves the current DNS record values as a reference baseline. On each check, it compares current values against the baseline and sends an immediate alert if any change is detected.

Common scenarios

• Attacker redirects your domain to a fraudulent server (DNS hijacking)
• Accidental DNS change during hosting migration
• Domain expiration followed by DNS record takeover
• Misconfiguration after deploying a new environment
