Urls behing Geocoding methods of Xamarin.Forms.Maps

Hello,
I have a problem where the GeoCoding methods are not working in a particular network. I believe it is due to the firewall blocking the url behind these methods. So It would help if you could provide me the Urls used behind the following methods, so that I can get them whitelisted in the network:
- GetAddressesForPositionAsync
- GetPositionsForAddressAsync

PS - Xamarin Forms Maps v2.4.0.74863
