Its not Android and iOS. It's operators providing IP->Customer lookup APIs!
Are you sure? Article seems to claim it's the OS.
Operators providing lookups is an issue in itself but seems not to be the issue here.
Oh. In this case they seem to be placing ads through Google's ad network?
Yeah and they claim a "MAID" ("mobile advertising ID") that iOS or Android provides is being sent to the ad server.
Googling "mobile advertising ID" yields lots of hits marketing this crap to advertisers, little technical info on mechanism/mitigation.
I dunno about Android but IIRC iOS has a semi-anonymized advertising IDs
IIRC they're unique per device&app combo
