Hello Emma, I was hoping someone with more knowledge than I have would have answered this, but I have a couple of suggestions: * OpenLayers, which has a geolocation module<https://openlayers.org/en/latest/apidoc/module-ol_Geolocation-Geolocation.html> and example at: https://openlayers.org/en/latest/examples/geolocation.html?q=geolocation. * Leaflet, which has an AccuratePosition plugin<https://github.com/M165437/Leaflet.AccuratePosition> and example at: https://m165437.github.io/Leaflet.AccuratePosition/ Both of these are open-source and use the W3C Geolocation API specification<https://www.w3.org/TR/geolocation-API/> which provides scripted access to geographical location information associated with the user’s device, by asking the user for permission to share their location, enabling the association of the user’s IP address with the detected location, mapping the result. These may be rather wide of the mark, as I suspect you are more interested in IP lookup services like https://ipstack.com/ or https://www.ip2location.com/, but I thought I'd quickly send in, just in case helpful.

Do not click links or open attachments unless you have verified the sender and know the content is safe. Hello All, I hope you are doing well. My colleague and I received a request from a fellow librarian to recommend a good open-source IP/geolocation mapping software that enables an IP address to be transformed into geographical location (X and Y coordinates). Are there any tools or packages that people have found success with?
