By default, Amplitude tracks the below user properties automatically via our SDKs. All the below properties will be prefixed with "[Amplitude]" in the platform. We use the collected IP address to reverse lookup a user's location user properties (City, Country, Region, and DMA). However, you can configure our SDKs to turn off tracking for these user properties.
Note: You will not be able to group by the user properties IP Address, Device ID, Event ID, Latitude, Longitude, Session ID, User ID, or ID due to high cardinality of possible values and you will have to input the exact values you are looking for if you choose to segment by them.
