# How to Add an IP Address to a VM?
The article contains instructions on how to manually add an IP address to servers with different operating systems.
To add an IP address, you will need to edit the network interfaces file. You can do this using standard OS editors. For example, in the Linux OS family, you can use the *vi*, *nano*, etc.
Example command to edit /etc/network/interfaces
```bash
vi /etc/network/interfaces
```
# IPv6 settings
To add an IPv6 address, you will need information about the network parameters. This information is available in the VM card: go to **Virtual Machines** → click on the VM name → **IP addresses** tab → **IPv6** tab → **Network parameters** button.
# AlmaLinux
To assign an IP address:
1. Connect to the server via SSH with superuser permissions.
2. To assign an IPv4 address
Specify the network settings in **/etc/sysconfig/network-scripts/ifcfg-<interface>** file, where <interface> is the name of the network interface. For example, /etc/sysconfig/network-scripts/ifcfg-eth0.
Example of settings
```bash
DEVICE=eth0
ONBOOT=yes
BOOTPROTO=static
IPADDR=192.168.1.100
NETMASK=255.255.255.0
GATEWAY=192.168.1.1
```
```
Comments to the example
DEVICE — interface name
IPADDR — IP address
NETMASK — network mask
GATEWAY — gateway IP address
To assign an IPv6 address
Add IPv6 settings to the network interface file **/etc/sysconfig/network-scripts/ifcfg-<interface>**, where <interface> is the interface name. For example, /etc/sysconfig/network-scripts/ifcfg-eth0.
Example of settings
```
```bash
IPV6INIT=yes
IPV6ADDR=2001:0DB8::/64
IPV6_DEFAULTGW=2001:0DB8::1
```
```
Comments to the example
IPV6ADDR — IPv6 address with network prefix
IPV6_DEFAULTGW — gateway IP address
```
1. Restart the NetworkManager software:
```bash
systemctl restart NetworkManager
```
1. Reconnect the network interface:
```bash
nmcli device disconnect <interface> && nmcli device connect <interface>
```
```
Comments to the command
<interface> — name of the network interface
```
# CentOS
To assign an IP address:
1. Connect to the server via SSH with superuser permissions.
2. To assign an IPv4 address
```
Specify the network settings in **/etc/sysconfig/network-scripts/ifcfg-<interface>** file, where <interface> is the name of the network interface. For example, /etc/sysconfig/network-scripts/ifcfg-eth0.

```
```
Comments to the example
DEVICE — interface name
IPADDR — IP address
NETMASK — network mask
GATEWAY — gateway IP address
To assign an IPv6 address

Example of settings

IPV6ADDR=2001:0DB8::/64
IPV6_DEFAULTGW=2001:0DB8::1
```
```
Comments to the example
IPV6ADDR — IPv6 address with network prefix
IPV6_DEFAULTGW — gateway IP address
```
1. Restart the NetworkManager software:
```bash
systemctl restart NetworkManager
```
# Debian, Ubuntu
To assign an IP address:
1. Connect to the server via SSH with superuser permissions.
2. Specify the network settings in **/etc/network/interfaces**:
To assign an IPv4 address
```
Example of settings
```
```bash
iface ens3 inet static
address 192.168.2.100
netmask 255.255.255.0
gateway 192.168.2.1
auto ens3
```
```
Comments to the example
ens3 — network interface
address — IP address
netmask — network mask
gateway — gateway IP address
To assign an IPv6 address
Example of settings
```
```bash
iface ens3 inet6 static
address 2001:0DB8::
netmask 64
gateway 2001:0DB8::1
auto ens3
```
```
Comments to the example
ens3 — network interface
address — IPv6 address
netmask — subnet prefix length
gateway — gateway IP address
```
1. Restart the *networking* service:
```bash
systemctl restart networking
```
# Assigning an IPv6 address in Windows
1. Connect to the virtual machine via VNC or SPICE. To do so, in VMmanager go to **Virtual machines** → click on the VM name → **VNC (SPICE)**.
2. Press Win + R and execute the command:
```bash
ncpa.cpl
```
1. Right-click on the network connection → **Properties**.
2. Check that **IPv6 (TCP/IPv6)** is enabled. Select it and click on **Properties**.
3. Enable the option **Use the next** **IPv6 address**.
4. Enter any IPv6 address from the subnet that VMmanager allocated for the server.
5. Specify the\*\* Subnet prefix length\*\* that VMmanager allocated for the server.
6. Specify the **Main gateway** of the physical network.
7. Click on \*\*OK \*\*to save the settings.
