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 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 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 configured properly, right click Start Menu, then click Command Prompt.

10. Execute the following command for checking network configuration.

    # ipconfig
    

CentOS – 8

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

   # /etc/sysconfig/network-scripts/ifcfg-eth1
   

Note: eth1/ens1 is the device name of the server. Please replace with the correct device name if necessary.

2. Add the following entries for network card and configure the static IP address.
   
   

   Example for 203.86.232.249:

   DEVICE=eth1
   ONBOOT=yes
   BOOTPROTO=static
   IPADDR=203.86.232.249
   NETMASK=255.255.255.0
   GATEWAY=203.86.232.1
   USERCTL=no
   

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

3. Save the file.
