Who’s going to be fingerprinting DHCP messages on your home network?

Outside of that, fingerprinting or tracking any DHCP info would be the least of my concerns. You have 0 control over any data the moment your devices connect to a public network. What use is DHCP info when you can person-in-the middle all the traffic anyway?

And anyway, what info are you concerned about? Having had a VERY quick browse of RFC2131 the worst thing would be “leaking” the device MAC address which can be discovered via several other means anyway
