What is 1e100.net?
The real reason they opted to do this, is make mobile firewalling more of a pain. If each application talked to the specific (types of) google services they needed, firewalling would be easier.<p>Instead, users cannot have a global rule to block <i>.1e100.net across their devices, due to this choice. In my case, this results in having literally dozens of rules - really one per application, in order to ensure that applications that are granted upstream internet access, are not granted </i>.1e100.net access unless I explicitly feel that they need access to Google Services.
