How To Disable IPv6 In Ubuntu

If you’re getting errors from squid or your web browser with some weird IP address, chances are that squid is trying to connect to a server which supports IPv4 and IPv6.

To disable IPv6 on Ubuntu (also Kubuntu), add this line to the end of /etc/sysctl.conf:

net.ipv6.conf.all.disable_ipv6 = 1

Restart your computer or reload sysctl.conf by executing: sudo sysctl -p

To check, run: ip a | grep inet6

When IPv6 is disabled, this will give no output.
