Ok ill inv u ill add more <| sep |> I ' m on TPG as well albeit in Sydney , but I ' ve never seen this happen . A quick Google indicates that you can view the DNS server in use on Android when not on wifi by typing the following command into a terminal app or adb shell . What does yours look like ? $ getprop grep dns That tells me that they ' re using a private DNS server in the 10 . 0 . 0 . 08 subnet same one they allocate IP addresses from , but that could just be a caching proxy . Could you give an example of a URL gets redirected to an ad page ? <| sep |> This answer is what I was looking for . What sort of expressiveness does Transit lack compared to EDN ? <| sep |> That ' s actually a good point now I think about it . edit Yea someone else pointed out how its not really going to effect performance . Bah .
