Cloud floating IP persistent

If you are using more than one floating IP, then the number on the interface (eth0:1) will be increased (example eth0:2)

On Debian based distributions (Ubuntu, Debian):

  • SSH into the server
  • Create the configuration file and open an editor
touch /etc/network/interfaces.d/60-my-floating-ip.cfg
nano /etc/network/interfaces.d/60-my-floating-ip.cfg
  • Paste the following configuration into the editor and replace your.float.ing.ip with your floating ip

IPv4:

auto eth0:1
iface eth0:1 inet static
    address your.float.ing.ip
    netmask 32

IPv6:

auto eth0:1
iface eth0:1 inet6 static
    address one IPv6 address of the subnet, e.g. 2a01:4f9:0:2a1::2
    netmask 64


  • Now you should restart your network. Caution: This will reset your network connection
sudo service networking restart

On RHEL based distributions (Fedora, CentOS):

  • SSH into the server
  • Create the configuration file and open an editor
touch /etc/sysconfig/network-scripts/ifcfg-eth0:1
vi /etc/sysconfig/network-scripts/ifcfg-eth0:1
  • Paste the following configuration into the editor and replace your.float.ing.ip with your floating ip

IPv4:

BOOTPROTO=static
DEVICE=eth0:1
IPADDR=your.float.ing.ip
PREFIX=32
TYPE=Ethernet
USERCTL=no
ONBOOT=yes

IPv6:

BOOTPROTO=none
DEVICE=eth0:1
ONBOOT=yes
IPV6ADDR=one IPv6 address of the subnet, e.g. 2a01:4f9:0:2a1::2/64
IPV6INIT=yes
  • Now you should restart your network. Caution: This will reset your network connection
systemctl restart network
