Disable IPv6 with OpenWRT - Super User
https://superuser.com/questions/110448424.07.2016 · I've tried a few things which haven't worked: turning off DHCPv6, disabling the DNS caching of dnsmasq, setting dnsmasq's DHCP server to provide a static DNS server address (8.8.8.8), and setting OpenWRT's internal DNS server setting to use that DNS server. How do I get OpenWRT to stop telling devices that it's OK to use IPv6?
