Just learning about data drain issues after bad experience with my Android phone on Topup credit.
And before we go any further,
YES, I know all about goodybags, thank-you. They're not usually cost-effective for me but I'm using one til this is sorted.
I had a message from Agent (swift and helpful) showing up to 4 data connections a day, e.g:
24/06/2013 08:19 172.25.23.16 1 2.4483522E7 bytes 4.67
i.e. for someone who almost never uses data, I just used a shedload and got charged £4.67 (actually it was £7.13 all in one day!)
a) What is this IP address? WHOIS responds with "Nominet is not the registry for this domain name". All my data connections in the agent report are to 172.25.xxx.yyy (xxx varies; yyy is either "16" or "19").
b) Anyone recommend an Android app to monitor data usage and connections so I can track down what's using the data.
172.25.xxx.xxx is within a private address range.
I've not got a easy way of proving this to hand at the moment but my guess is that this is within the giffgaff network (rather than the public internet) and probably the address of the link your phone is using to the public internet (which changes from time to time - you don't have a static "public" IP address).
That's why WHOIS is not much use in this case.
Something on your phone is attempting to get updates regularly.
Do you have any new games or apps ?
I like NetCounter for Android data monitoring but I've never seen anything which gives usage by each app.
Stadium is on the money with the point about this being a private address range, this range is what companies will use on their internal networks similar to the common 192.168.x.x domestic routers frequently use.
I wonder if you use a wifi network that gives you an IP address in the 172.25.x.x range and you connect to a server or device in that network at 172.25.23.16, and it continues trying once you move out of range of the network, and those attempts go over the mobile network?
There are firewall apps available for android, as a last resort you could install such an app and set up rules to disallow traffic to that IP range.
Thanks to all for the replies. Don't think we've got anywhere though.
@endorphin & w69d - I'm on Samsung so iphone unlikely to be relevant.
I'm also on Android 2.something (Galaxy Y) so I don't have "data usage" on my handset.
I'll try my data manager and see if that helps.
