Make sure your flexible IPv6 is attached to your Elastic Metal server before configuring it.
How to configure a flexible IPv6 on an Elastic Metal server
The configuration of a flexible IPv6 depends on the Linux distribution running on your machine. You can configure your flexible IPv6 on machines running Debian, Ubuntu, or CentOS.
Before you start
To complete the actions presented below, you must have:
- A Scaleway account logged into the console
- Owner status or IAM permissions allowing you to perform actions in the intended Organization
You can find information about the DNS resolver to use in each datacenter at the network reference documentation.
How to configure IPv6 on Debian
-
Open the network configuration file
/etc/network/interfaces
in a text editor and edit it as follows:auto eno1iface eno1 inet6 staticaddress IPV6_ADDRESSnetmask 64Remember to replace
eno1
with the proper internet interface name. -
Restart the network:
sudo systemctl restart networking.service
The network interface is initialized with the command allow-hotplug
by default on Debian 9. It is possible that the network restart fails with this configuration. In this case, you can initialize the network with auto
to avoid the problem.
How to configure IPv6 on Ubuntu
Ubuntu uses netplan as network configuration tool since the release of Ubuntu 18.04 LTS.
It replaces the classical network configuration with new configuration files, written in YAML format, and located in the /etc/netplan
directory. For more information regarding netplan, refer to the official netplan documentation.
-
Open the default configuration file
/etc/netplan/01-netcfg.yaml
in a text editor, and edit it as follows:# This is the network config written by 'subiquity'network:ethernets:eno1:critical: truedhcp-identifier: macdhcp4: trueaddresses: [ "IPV6_ADDRESS/64" ]nameservers:addresses:- 51.159.47.28- 51.159.47.26search:- online.netversion: 2Remember to replace
eno1
with the proper name of your internet interface.NoteThe configuration example above is valid for the main IP address of your Dedibox server. If you want to use IPv6 on a virtual machine, remember to use the unique gateway for the failover IPv4.
-
Check and validate your configuration file.
sudo netplan try -
Activate the new configuration:
sudo netplan apply
How to configure IPv6 on CentOS
- Open the automatically generated configuration file for your internet interface in a text editor, for example
/etc/sysconfig/network-scripts/ifcfg-eth0
and edit it as follows:# Generated by parse-kickstartUUID=xxxxxDNS1="51.159.47.28"IPADDR="DEDIBOX_MAIN_IP"GATEWAY="DEDIBOX_MAIN_IP_1" # The IPv4 gateway is your servers main IP address ending on .1 (e.g. Your servers IP is 62.210.16.123 means the gateway is 61.210.16.1)NETMASK="255.255.255.0"IPV6ADDR="IPV6_ADDRESS/64"IPV6_AUTOCONF="yes"BOOTPROTO="static"DEVICE="eth0"ONBOOT="yes"IPV6INIT="yes" - Restart the networking service:
systemctl restart network.service
