disable IPv6 on a specific interface (linux)

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.

this article hit pretty close to home this weekend when the TED radio hour came on and i had to ask alexa to shut it down because i couldn’t take the breathless delivery of the presenter spouting TED cliches. the tl;dr - TED’s about to become as vacuous as any other religion; titillating the senses and delivering pablum. the author doesn’t call it out in this manner. but they do a nice job of pointing out that TED’s veered into the trivializatin of things and the presentation of real problems as “puzzles to be solved....
