IP adresses aren’t fixed (for most people), just disconnect your modem for a few hours and you’ll probably get a new one.
The issue is not that it’s static, the issue is that it is getting assigned by an authority. In the solution the random ID is generated on device
You are being tracked by cookies, browser fingerprints, only being able to use a website after logging in, etc.
Although that is possible, my understanding is that the most significant information regarding one’s location and identity, after an account, is the IP.
The cookies and so on are the “account.” And the trackers are sophisticated enough that they can track you across multiple devices, meaning multiple IPs.
Does your imagined network protocol also not have MAC addresses? At some level a packet needs to know where it is going, or the receiver won’t get it.
IPs change, maybe you’re at home, maybe on mobile, maybe at the office, maybe at a friend’s house. The aggregate fingerprint of the remaining parameters, is way better at uniquely identifying anyone, then linking any information that “anonymous unique identity” leaves behind to create a profile that over time becomes easier and easier to deanonymize.
You are not logged in. However you can subscribe from another Fediverse account, for example Lemmy or Mastodon. To do this, paste the following into the search field of your instance: !programming@beehaw.org

Notice how the IP is not even on the list.
