Thanks Bjørn for your response. I think I am getting a bit confused here.

I booted up my Linux VM and set the following in my /etc/sysctl.conf file:

net.ipv6.conf.all.disable_ipv6=1
net.ipv6.conf.default.disable_ipv6=1

I saved the file.

*I rebooted my VM.*

After reboot, I check the value of
"/sys/module/ipv6/parameters/disable_ipv6". *It is still 0.*

As it is still 0, the new namespaces are created with IPv6 enabled. Is this
a bug in the kernel code?
