Privacy concerns with DHCP (DHCP fingerprinting) (lemmy.zip)

So many people here will go though great lengths to protect themselves from fingerprinting and snooping. However, one thing tends to get overlooked is DHCP and other layer 3 holes. When your device requests an IP it sends over a significant amount of data. DHCP fingerprinting is very similar to browser fingerprinting but unlike the browser there does not seem to be a lot of resources to defend against it. You would need to make changes to the underlying OS components to spoof it.

What are everyone's thoughts on this? Did we miss the obvious?

Long story short, don't look for privacy on local Ethernet segment :D

You seem to be forgetting that a lot of people use portable devices on other networks than their home one.

i am not forgetting anything. using your portable device on network other than your own is your free choice and if you are such control freak that you are afraid of being spied on through dhcp, you probably should not do that.
