Using Angular Maps Components and a new service called ipapi, you will be able to quickly put together something that will allow you to get IP information from a client and put it on a map.
Angular Maps Components is really great, and the setup with ipapi is a no-brainer (they have a free tier for 30,000 requests or under). It literally took me more time to wait for the angular project to be set up than to implement the whole thing!
The code is in github: https://github.com/danielpradilla/angular-ipapi
