Today I made my first native IPv6 connection. I've been running Teredo/Miredo on my laptop for quite a while now, and I thought it was time to get a real IPv6 connection. I could use IPv6 autoconfiguration, but on a server you need a fixed IP.
Install required packages that are not included in the Fedora default install:
yum install iproute2 ndisc6
Configuring the network is not that much different from configuring an IPv4 address.
|ip addr add 188.8.131.52/24 dev eth0||ip addr add 2001:1BE8:DEAD:BEEF::1a1a/64 dev eth0|
|ip route add default via 184.108.40.206||ip route add default via 2001:1BE8:DEAD:BEEF::1|
Now test it by pinging/tracerouting some known IPv6 services:
[root@localhost ~]# ping6 ipv6.google.com

Configure at boot time
Step 1. Enable IPv6 networking
then add (or replace):
Step 2. Configure IPv6 addresses
then add the following lines:
Step 3. Test
service network restart or reboot to test.
Warning: if you do this remotely, you may lose the connection. I first locked myself out of my test machine, but I always got a KVM switch attached or VMWare console.
Please remember that using IPv6 also means that there's a new entrance to your network. Use ip6tables to set up a firewall.
Ubuntu/DebianI'm running RedHat-based software on all of my machines. Above information may be useful for Ubuntu/Debian users, but it's not tested and I'm not supporting it.
Servers: RedHat Enterprise Linux/CentOS is more suitable for servers, as there's a lot of professional level support available. I think that's important, because if I say, get a car accident, I want the servers to be managable by another professional.
Desktops/Laptops: RPM packages are pretty exchangable between RedHat-based platforms. That's a good reason to run Fedora on the desktop.
