IPV6 is the most recent version of internet protocol (IP) designed to eliminate the long-anticipated address exhaustion problem of IPV4. In order to disable IPV6 on Linux/Ubuntu, please follow the steps below:

1 Open Terminal

2 Enter gksudo gedit /etc/sysctl.conf and open the configuration file and add the following lines at the end

net.ipv6.conf.all.disable_ipv6 = 1

net.ipv6.conf.default.disable_ipv6 = 1

net.ipv6.conf.lo.disable_ipv6 = 1

3 After that run $ cat /proc/sys/net/ipv6/conf/all/disable_ipv6

If it reports ‘1′ means you have disabled IPV6. If it reports ‘0‘ then please follow Step 4 and Step 5.

4 Type command sudo sysctl -p you will see this in terminal.

net.ipv6.conf.all.disable_ipv6 = 1

net.ipv6.conf.default.disable_ipv6 = 1

net.ipv6.conf.lo.disable_ipv6 = 1

5 Repeat above “Step 3” and it will now report 1.
