The Fedora distribution is a cutting edge project that often showcases new technologies. James Hogarth has a write-up of some new changes coming soon to Fedora users, specifically new functionality in NetworkManager. Hogarth's post talks about privacy features for use on wireless networks, bridging connections and what to expect from NetworkManager in the upcoming release of Fedora 26: "Just as recently as Fedora 24 (and EL7.3) NetworkManager began using a random MAC whilst scanning for access points to use. The default at present is to use whatever the MAC of the interface is (or preserve if it’s been set in advance with a tool like macchanger) however similar to the IP layer it’s now possible to set cloned-mac-address on a connection to RANDOM for a totally random MAC each time that connection is activated or STABLE to mimic the IPv6 behaviour of a randomly generated address that stays consistent with a connection." The post on Fedora Magazine has more details.
