It's also a great news for Malware too as they usually check for their remote IP. But maybe that will be another way of Google to detect if the local machine is infected in a near future.
Malware usually opens a reverse (TCP) connection and thus does not require the remote IP of the infected machine. It only needs to know the IP or domain name of the server it wants to communicate with.
I don't get why my previous comment is down-voted ;-)
