How to configure the Static IP Address & Network Card for Linux & Windows Cloud Servers

Every Cloud Servers will include a public IP address through which the server can be accessed remotely. The IP can be set as either DHCP (automatic) configuration or static IP configuration. DHCP configuration detects IP address setting automatically, whereas static IP configuration requires the IP address settings to be manually set in the server.

This guide outlines the basic steps on how to configure the IP address of your server manually in your Linux or Windows Cloud Servers. The same steps can also be used to update the new IP address in the server manually.

Windows OS

1. Click Start Menu, then click Control Panel option.

2. Click Network & Sharing Center option.

3. Click Change adapter settings in the left panel.

4. Right-click adapter with the name Ethernet and select Properties.

5. In the properties window, select Internet Protocol Version 4 (TCP/IPv4) and click Properties button.

6. Select Use the following IP address: option and configure the static IP address.
   
   

   Example for 203.86.232.249:

   

   Note: The netmask is 255.255.255.0 and the gateway is 203.86.232.1.

7. Once IP and Subnet are entered, check the box Validate Settings upon exit, click OK and then close the Ethernet property window.

8. Windows Network Diagnostic tool will run to check to see any issues, close this window.

9. To check if the static IP address is configured properly, right-click Start Menu, then click Command Prompt.

10. Execute the following command for checking network configuration.

    # ipconfig
    

AlmaLinux

1. Edit the network configuration file using the below command.

   # vi /etc/sysconfig/network-scripts/ifcfg-ens3
   

   NOTE: ens3 is the device name of the server. Please replace with the correct device name if necessary.

2. Change the value of BOOTPROTO to static from dhcp and then add the following entries in the network card to configure the static IP address.
   

   Example for 203.86.232.249:

   BOOTPROTO=static
   DEFROUTE=yes
   DEVICE=ens3
   DNS1=8.8.8.8
   GATEWAY=203.86.232.1
   IPADDR=203.86.232.249
   NETMASK=255.255.255.0
   ONBOOT=yes
   STARTMODE=auto
   TYPE=Ethernet
   USERCTL=no
   

   Note: The netmask is 255.255.255.0 and the gateway is 203.86.232.1.

3. Save the file.

4. Restart the network service and make the changes effect.

   # nmcli networking off
   # nmcli networking on
   

5. Check the static IP address configured properly inside the network card.

   # ip a
