Debian 8 jessie : Disable ipv6 support
i know some people will say we should start using ipv6 ! ... and i'm mostly agree with them ... BUT i'm still no expert with ipv6 and i have WEEEEIIIIRD behavior on my network because of it ...
so for the moment i'm trying to disabled it on all my new jessie.
To do so just edit your /etc/sysctl.conf file and add these lines :
After editing sysctl.conf, you should run sysctl -p to activate changes or reboot system.
