I'm currently using the URL http://services.arcgisonline.com/ArcGIS/rest/services/World_Street_Map/MapServer for my iPad map service.
However, we need to connect to VPN to access the internal network at the same time, and the VPN server blocks the public Internet, and only allows me to setup IP Address based public Internet access.
Is there static IP addresses associated to the above URL that I could specify?
