Monitor DNS Changes

Check DNS records and WHOIS data to detect unauthorized or unexpected changes to your domain configuration.

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.
