This is not a safe method for protecting against this type of cache vulnerability. IP addresses are regularly shared by multiple users, especially when behind NAT (even mobile ISPs are doing carrier grade NAT these days).

So there should be no fail safe since it can't be guaranteed to work in every scenario.
