because i have to google these sysctl settings every … time..
/etc/sysctl.conf
# disable IPv6 on the wlan0 interface
net.ipv6.conf.wlan0.disable_ipv6=1 # insufficient on its lonesome
net.ipv6.conf.wlan0.autoconf=0 # don't forget this ..
it’s important to disable autoconf because it will still pick up the RAs for
learning the default and this may not deterministically let you do what you
want.
replace wlan0 with the interface you want to starve.
