I am trying to set up a CentOS 5.4 box to use a static IPv4 address, while getting a dynamic IPv6 address at boot time.

I have only one interface, apart from the loopback interface, eth0. It has a static v4 and internet connectivity (I can SSH in). However, it doesn't get an IPv6 by default.

I have enabled IPv6 in /etc/sysconfig/network and I have added IPV6INIT=yes to the config in /etc/sysconfig/networking/devices/.

If I use dhcp6c it does get a valid IPv6 address, but the main question is how do I configure it to get one at boot-time?

HTG Explains: Are You Using IPv6 Yet? Should You Even Care?

IPv6 is extremely important for the long-term health of the Internet. But is your Internet service provider providing IPv6 connectivity yet? Does your home network support it? Should you even care if you’re using IPv6 yet? Switching from IPv4 to IPv6 will give the Internet a much larger pool… >>> More
