IP Addressing: Field Application

Field Scenario

A customer asks why their computer shows a different IP address using this site’s IP lookup tool than what appears in their router’s local network settings.

What You Actually Explain

  • This reflects the real distinction between private (local network) and public (internet-facing) IP addresses
  • The IP lookup tool shows the public address, while router settings show the private local address
  • This is normal, expected behavior, not an error or problem
  • Understanding this distinction is foundational to interpreting network diagnostic tools correctly
