Is it possible for the Email-to-Case functionality to recognise the Country of the originating Email by IP Address?

When Email-to-Case creates a Case, we would like to automatically update the Country (custom picklist) field on case object based on IP address. or if any other way to do it I please let me know.

Any thoughts would be greatly appreciated.
 

Thanks!

is there any way to check duplicate file is being uploaded?

based on name is one way but there can be two different files with same extension but with different content..

is there any way in LWC js or apex that so based on unique file id we can identify?
