Part one of many.
Google publishes JSON files with IP ranges for various services, including Google cloud. They don’t see fit to include all of the ranges, though. They’ve chosen to populate RDNS for at least one of those ranges I’ve found, so there is very little question that it’s an omission. With Google, it’s safe to assume that all such omissions are intentional. With the number of employees they have and their alleged intelligence, this situation should properly be utterly impossible as an accident. They’re just too smart, right?
The problem when you tell people they’re the smartest is that they wind up doing incredibly stupid things, thinking that it’s invisible to everyone else. It’s not invisible, Google. We see you, and we’re judging you. The judgement is that you’re trying to be sneaky for whatever reason.
I don’t purchase Google services. Google isn’t good enough. This is one more reason why.
