#1 Denshi Video fan (npub1css…khug) John Paul Grips (npub175d…wrtj) Unless the BIOS is surreptitiously sending surveillance packages, it's not possible to detect what BIOS is being used via IP.
Some computers have a hardcoded MAC with per-model address allocations that can be used to correspond with the hardware model, although the false positive rate would be too high, considering that GNU macchanger could possibly select a random MAC within the blacklisted MAC range.
Proprietary OS's do have a detectable IP header encoding and it would be possible to drop packets that clearly came from computers running windows, macos or any of the BSDs, although it wouldn't be possible to differentiate between proprietary GNU/Linux and free GNU/Linux-libre.
