Builds on: Telecom (Part 3): IPDR and Lawful Interception

Unit 10A15 minEnglish

From IP Address to Person

Readiness training. LEA.Training does not grant any official certificate, licence or authority.

A log shows an IP address. A provider gives a name for it. It is easy to stop there and say "this person did it". That step is where cases go wrong.

Focus: an IP address points to a connection at a time. It does not name a person. This unit shows each link from address to person, and where each can break. It is general knowledge. It is not legal advice.

Learning objectives

  • Explain why an IP address needs an exact time, a time zone and often a port.
  • Describe how shared addresses, shared Wi-Fi and VPNs weaken the link to one person.
  • State the limits of a location database and a registry record.
  • Explain what a network can still see when traffic is encrypted.
