When to Check an IP

📧 Suspicious Emails Check the sender's IP in the email headers to verify if it's from a trusted server or a known attack range.
🌐 Unknown Connections If you see an unexpected connection in your router logs or firewall, check that IP's origin.
🛒 Fraud Prevention High-risk IPs (datacenters, VPNs) are frequently used by fraudsters to fake location or identity.
