IPv6 is now compatible with all of our dedicated and KVM VPS servers. To enable IPv6 inside your KVM virtual server you need to edit the etho file and add a route6 file into your servers networking scripts. The route6 file is optional but we advise to add one anyway.

These KVM IPv6 settings are unique to our network and will not function with KVM virtual servers with other providers. Consider a KVM VPS server from First2Host. Build the virtual server you require with the resources that you need and never pay for resources you’re not going to use again.

CentOS

First, we need to make some changes to the eth0 file to enable IPv6 inside the virtual machine. It’s important you take a backup of the file so we can revert back to the default settings. If something goes wrong you can also login to your VPS control panel and hit “reconfigure networking”

cp /etc/sysconfig/network-scripts/ifcfg-eth0 /etc/sysconfig/network-scripts/bkifcfg-eth0

Add an IPv6 resolver into your resolv.conf file. We’re using Googles. Just paste the nameservers to the bottom of the file and save

nano /etc/resolv.conf

nameserver 2001:4860:4860::8888 
nameserver 2001:4860:4860::8844

Now let’s edit the eth0 file open the file in nano and paste the below code into the bottom of the file.

nano /etc/sysconfig/network-scripts/ifcfg-eth0

IPV6INIT=yes
IPV6_AUTOCONF=no
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
IPV6ADDR=
IPV6_DEFAULTGW=2607:5300:60:78ff:ff:ff:ff:ff

The file should look like this when you have finished

Some things to point out;

The IPv6 must be in its full form including CIDR notation at the moment we use /64 IPv6 blocks

To assign additional IPv6 addresses just enter them on a new line, when your server is setup we already route these to your machine they simply need placing in the file.

Now let’s create the route6 file

nano /etc/sysconfig/network-scripts/route6-eth0

Now inside that file specify the gateway for IPv6

2607:5300:60:78ff:ff:ff:ff:ff dev eth0
default via 2607:5300:60:78ff:ff:ff:ff:ff

Save and close the file CNTRL+X

Restart the network

service network restart

After the network has restarted your server is now IPv6 ready and you should be able to contact your IPv6 address. If you can’t please contact our support team.
