Yes, the system sends out IPv6 Neighbor Discovery messages and listens for IPv6 Router Advertisement messages. This all happens automatically by default in Fedora thanks to the hard work that has gone into enabling IPv6 by default in the OS, applications, and services. If you are on a network that supports IPv6, it all Just Works(TM), just the same as IPv4 has up to this point. > If it isn't used, then free up the unused resources. IMHO the resource argument is a red herring. Perhaps we should not ship GNOME by default because it uses too much resources? OTOH, perhaps we should disable IPv4 by default, or free all kernel resources related to IPv4 if there is no response from an IPv4 DHCP server? I don't think these are very good arguments. -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
