When you order an extra IPv4 address or add an extra IPv6 address to your IP addresses via the TransIP control panel, these cannot be automatically added to your VPS via DHCP. Additional IP addresses are added manually to the network interfaces.
In this article, we explain how you can statically add an extra IPv4 or IPv6 address to your Debain 8 VPS. For this, an extra IPv4 and/or IPv6 address is required (depending on which you'd like to add / configure). Don't have an extra address yet? The following articles explain how you can get one:
- Ordering an extra IPv4 address in the control panel
- Creating an extra IPv6 address in the control panel
Click here for a complete overview of all our tutorials for adding an extra or static IPv4 or IPv6 address to various Linux distros. For adding an IPv4 or IPv6 address to a Windows VPS, see this article.
- This manual is about public IP addresses. In this manual, you will find more information about setting up internal addresses (for your private network).
A VPS includes 1 IPv4 address by default, but you can expand this to a maximum of 10 IPv4 addresses via the control panel. A maximum limit of 20 IPv4 addresses applies to the VPSs of the PRO series.
Each VPS has a /64 IPv6 range at its disposal by default, where IP addresses can be added as desired. A /64 IPv6 range contains a total of 18,446,744,073,709,551,616 IP addresses, so the likeliness that you will not have enough is quite small! The default gateway falls outside of the /64 range so as netmask you always use a /48 range.
Adding an IPv4 address in Debian 8
Step 1
Connect to the VPS via the VPS console or via SSH.
Step 2
Once logged in you see the current network interfaces and the set IPs by means of the command:
ifconfig -aFor the next steps, it is especially important that you are aware of the correct adapter name. Which is eth0 in this example.
Step 3
Now add the extra IPv4 address in the network interfaces. First, open the network configuration file:
sudo nano /etc/network/interfacesPlease note that if you have already set an extra IP address to eth0:0, that you use the next interface (i.e. eth0:1).
A configuration file should be opened where the main IPv4 address should already be set and you enter the following:
auto eth0:0
allow-hotplug eth0:0
iface eth0:0 inet static
address 149.210.202.105
netmask 255.255.255.0
IPADDR is the IP address that you want to add and can be found in the control panel. Leave the (sub) NETMASK at 255.255.255.0.
With two additional IP-addresses your file may look like this:
# The prmary network interface
allow-hotplug eth0
iface eth0 inet dhcp
# This is an autoconfigured IPv6 interface
iface eth0 inet6 auto
auto eth0:0
allow-hotplug eth0:0
iface eth0:0 inet static
address 149.210.202.105
netmask 255.255.255.0
auto eth0:1
allow-hotplug eth0:0
iface eth0:0 inet static
address 149.210.202.106
netmask 255.255.255.0Save the changes and exit nano (ctrl + x > y > enter). For additional IPv4 addresses, add eth0:1, eth0:2, and so on.
Step 4
Reset your network interfaces with the following command to use the new IP address:
sudo service networking restart
Step 5
If you run ifconfig -a again you will see the newly added IPv4 address. You can test this IP address by performing a ping test from another computer / IP.
Adding an IPv6 address in Debian 8
Step 1
Connect to the VPS via the VPS console or via SSH.
Step 2
Once logged in you see the current network interfaces and the set IPs by means of the command:
ifconfig -a
For the next steps, it is especially important that you are aware of the correct adapter name. Which is eth0 in this example.
Step 3
Now add the extra IPv6 address in the network interfaces. First, open the network configuration file:
sudo nano /etc/network/interfaces
In the opened configuration file, add the following lines:
address 2a01:7c8:aab8:77::1337 netmask 48 gateway 2a01:7c8:aab8::1
The address is the IP address that you want to set and GATEWAY the gateway, which for your IP address can be found in the control panel. You need to leave the (sub) NETMASK at 48. Save the changes and exit nano (ctrl + x > y > enter).
Step 4
Reset your network interfaces with the following command to use the new IP address:
sudo service networking restart
Step 5
If you run ifconfig -a again you will see the newly added IPv6 address. You can test this IP address by performing a ping test from another computer / IP.
Repeat the above steps if you want to add more IP addresses.
