How do I recognize if a DNS record has been tampered with?

1. Use tools like nslookup 或 挖掘 to check your DNS records.
2. Compare the returned IP addresses with the expected ones.
3. If you see any unfamiliar IP addresses, it could indicate tampering.
4. Regularly monitor DNS changes to catch unauthorized modifications.
5. Implement DNSSEC for added security and protection.
