# Monitor DNS Changes

Unauthorized DNS changes can redirect your traffic, intercept your email, or take down your services. Whether caused by a compromised registrar account, an accidental edit, or a malicious attack, detecting DNS changes quickly is critical for minimizing damage.

Using lookup_dns and whois_lookup, you can inspect the current state of your DNS and domain registration. Compare records against your known-good configuration to spot unauthorized changes. Check WHOIS data to verify ownership details and registration status have not been tampered with.

**Tool:** [DNS Domain](https://toolrouter.com/tools/dns-domain)
