Load Balancing DNS queries with Geolocalization from Cell Phones via APNs

I don't think you are going to be able to do this within the DNS protocol, as there is no X-FWDR type functionality.

But, I am still not sure why you would want to do this. Once again, I am not a cellular guy, so not sure how these APNs fully work. I am just applying what I know about Enterprise Internet Proxies. If they have DHCP style IP ranges they assign to phones they proxy, and use IP that is geolocated, it would seem using the phone's IP would only make it less accurate.

Do APNs have to assign IP ranges that are geographically accurate? OR do they only have to be at the public side of the APN?
