What’s the benefit of employing various aliases, email accounts, and browsers to navigate the web on the same computer, when your IP address stays constant across all sites and is tracked and correlated by Google on the majority of them?
Your public IP is irrelevant because it’s the device inside your local network that matters. IP addresses are shuffled around all the time. However if your device exhibits behaviors that are consistent across multiple visits across multiple sites then you can be fingerprinted.
Your public IP address is a single address that may apply to many many different devices. Your IP address can change daily. In fact there is a decent chance that if you reboot your router you’ll end up with a different IP address.
The only reliable way to track you is using fingerprinting.
If you’re trying to not be tracked you need to protect your IP. There’s a lot more but that’s the basic first step
This is incorrect. Dynamic Public IP addresses are shifted all the time. Device fingerprinting is what matters.
It depends on your threat model. If you’re concerned with smaller services getting a strong handle on your identity (e.g. a porn site knowing your actual name), then leaking your IP address may not be a problem.
If you’re worried about your online actions being traced back to you by Google then using a VPN to limit your exposure may help.
If you’re worried about three letter agencies, I’d assume that most VPNs are compromised and try to avoid doing anything online.
Just use a VPN and avoid always using the same server?
