CentOS / Red Hat IPv6 Network Configuration

Setting up IPv6 on CentOS, and for that matter RHEL and Fedora Linux, is quite straight forward. You need to edit just two files:

1. /etc/sysconfig/network-scripts/ifcfg-
2. /etc/sysconfig/network

1. Configure the IP address. For example, for interface eth0, edit /etc/sysconfig/network-scripts/ifcfg-eth0 and make the necessary changes as below.DEVICE=eth0
HWADDR=00:22:15:17:CC:C1
BOOTPROTO=static
IPADDR=192.168.1.2
NETMASK=255.255.255.0
NETWORK=192.168.1.0
BROADCAST=192.168.1.255
IPV6INIT=yes
IPV6_AUTOCONF=no
IPV6ADDR=<ipv6 address>
ONBOOT=yes
