A DNS Change Can Hijack Your Website
DNS changes are silent and instant. A misconfiguration, a compromised registrar account, or a deliberate hijack can redirect your visitors, intercept your email, and destroy user trust — all without any obvious outage signal. DrMonitor compares your live DNS records against a known-good baseline on every check and alerts you the moment anything changes.
Start for freeYour DNS records compared against a known-good baseline every check
The first time DrMonitor scans your domain, it records every DNS record as your trusted baseline — A, AAAA, NS, MX, CNAME, TXT, and CAA. On every subsequent check it compares the live records against that baseline. Any deviation triggers an alert with a full diff showing exactly what changed, what it was before, and what it is now.
- Monitors A, AAAA, NS, MX, CNAME, TXT, and CAA record types
- Baseline set automatically on first check — zero configuration needed
- Full diff logged — old record vs new record for every changed type
- Baseline auto-updates after you confirm a legitimate change
The first sign of DNS hijacking is a record you didn't change
DNS hijacking often starts small — an NS record pointing to a different nameserver, an A record redirecting visitors to a lookalike site, or an MX record intercepting your business email. These changes can persist undetected for hours. DrMonitor catches them in the next monitoring cycle and fires an alert with a clear recommendation to secure your registrar account immediately.
- Detects unauthorized NS, A, MX, and CNAME record changes
- Alerts include a direct recommendation to enable 2FA and transfer lock
- Debounced alerts — one notification per hour to avoid noise floods
- Full change history stored — every DNS diff logged with timestamp
A hijacked DNS kills your rankings, email, and visitor trust instantly

Google may flag your site as dangerous, wiping your organic rankings overnight. With DrMonitor watching every DNS record, you get the earliest possible warning to stop an attack before it causes lasting damage to your business and SEO authority.
