I've just upgraded to FC4 (clean install), and I'm just in the process of merging setting from my old FC3 /etc into the new one. I prefer to disable IPv6 completely as it seems (or seemed) to speed up things like web browsing. Previously I did this by adding
alias net-pf-10 off alias ipv6 off
to modprobe.conf. Is that still necessary, or is simply unchecking "Enable IPv6 configuration for this interface" in
Desktop -> System Settings -> Network -> <device> -> Edit
sufficient?
TIA.
