+                    <p>GrapheneOS supports per-connection MAC randomization and enables it by
+                    default. This is a more private approach than the standard persistent
+                    per-network random MAC used by modern Android.</p>
+
+                    <p>When the per-connection MAC randomization added by GrapheneOS is being
+                    used, DHCP client state is flushed before reconnecting to a network to avoid
+                    revealing that it's likely the same device as before.</p>
+
+                    <p>GrapheneOS also applies fixes for serious flaws with the Linux kernel IPv6
+                    privacy address implementation which allow using it as an identifier not just
+                    for connections to the same network but also across different networks. We
+                    don't need to apply these changes for the Pixel 6 and later since this was
+                    fixed in the Linux kernel upstream, but hasn't been backported to earlier
+                    kernel LTS branches so we still need to take care of it there.</p>
