Although IPv6 has many advantages over IPv4, few organizations have implemented IPv6.
Rationale:
If IPv6 is not to be used, it is recommended that it be disabled to reduce the attack surface of the system.
Fix:
Create or edit the file /etc/sysctl.conf and add the following lines:
net.ipv6.conf.all.disable_ipv6=1 net.ipv6.conf.default.disable_ipv6=1 net.ipv6.conf.lo.disable_ipv6=1
Run the following command or reboot to apply the changes:
# sysctl -p
Parameter:
[yes/no]
Technical Mechanism:
Create or edit the file /etc/sysctl.conf and add the following lines:
net.ipv6.conf.all.disable_ipv6=1 net.ipv6.conf.default.disable_ipv6=1 net.ipv6.conf.lo.disable_ipv6=1
Run the following command or reboot to apply the changes:
# sysctl -p
