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 versions before 20.04, Debian):

1. Access the server via SSH.

2. 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

3. 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

4. Now you should restart your network. Caution: This will reset your network connection:

   sudo service networking restart

Ubuntu 20.04:

1. Access the server via SSH.

2. Create the configuration file and open an editor:

   touch /etc/netplan/60-floating-ip.yaml
   nano /etc/netplan/60-floating-ip.yaml

3. Paste the following configuration into the editor and replace your.Float.ing.IP with your floating IP: IPv4:

   network:
   version: 2
   ethernets:
    eth0:
      addresses:
      - your.float.ing.ip/32

IPv6:

 network:
   version: 2
   ethernets:
     eth0:
       addresses:
       - your.float.ing.ip/64

4. Now you should restart your network. Caution: This will reset your network connection:

   sudo netplan apply

On RHEL based distributions (Fedora, CentOS):

1. Access the server via SSH.

2. Create the configuration file and open an editor:

   touch /etc/sysconfig/network-scripts/ifcfg-eth0:1
   vi /etc/sysconfig/network-scripts/ifcfg-eth0:1

3. 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

4. Now you should restart your network. Caution: This will reset your network connection:

   systemctl restart network
