IP LensHow to read an IP address, location and ASN
An IP lookup helps you understand the address a service sees and the network associated with it. It cannot establish who is using that address or exactly where they are. This guide explains how to gather useful evidence without reading too much into a result.

A useful DNS check starts with a specific question: which address should this name resolve to, where should mail go, or has a recent record change become visible? Choose the relevant record type before interpreting a response.

IP Lens provides two different checks: WebRTC candidate gathering and a local summary of browser properties. Use them for a specific diagnostic question. Neither is a universal privacy score or a certificate of anonymity.

A connection can behave differently over IPv4 and IPv6, and a successful address lookup does not explain every slow page. These separate checks help you gather a few useful observations before changing your setup.

Run only the checks you need, use targets you are authorized to investigate, and record the time and data source when comparing results. These guides describe the current browser tools, including their limits.
