IPV6 Becoming Invasive & Identifying How to Disable in Linux

[shotgun00]

This should allow you to disable completely Ipv6:

Add these lines to the bottom of sysctl.conf

net.ipv6.conf.all.disable_ipv6 = 1

net.ipv6.conf.default.disable_ipv6 = 1

net.ipv6.conf.lo.disable_ipv6 = 1

Then run sudo sysctl -p or reboot

This of course won't stop bind from blindly trying to use ipv6 though, so you also need to alter /etc/default/bind9 like so:

# run resolvconf?

RESOLVCONF=yes

# startup options for the server

OPTIONS="-4 -u bind" -
