I am using Fedora linux kernel When I list kernel modules using lsmod command, I did not find any IPv6 module.

Then I have used the following document to load the module

[root@localhost ~]# test -f /proc/net/if_inet6 && echo "Running kernel is IPv6 ready"
Running kernel is IPv6 ready

[root@localhost ~]# modprobe ipv6
FATAL: Module ipv6 not found.

Any suggestion why I am getting this FATAL error
