Things to Remember Before Changing VPS IP 

Before changing your VPS IP address, there are several important things to keep in mind:

2. Update DNS records to reflect the new IP address to avoid downtime. 

3. Ensure your new IP address is not blacklisted by service providers to prevent email deliverability issues.

5. Be prepared for downtime during the IP address change process. 

6. Monitor the server after the change to ensure everything is functioning correctly. 

How to Change IP Address on Ubuntu? 

To change the IP address on Ubuntu, you can use the following steps: 

1. Open Terminal: Press Ctrl + Alt + T to open a Terminal window. 

2. Check Current IP Address: Use the ifconfig command to check your current IP address and network interface name. For example, to check the IP address of your Ethernet interface (eth0), you can use: 

ifconfig eth0 

3. Change IP Address: You can change the IP address either temporarily or permanently. 

  • Temporary Change: Use the ifconfig command to change the IP address temporarily. For example, to change the IP address of the eth0 interface to 192.168.1.100, you can use: 

sudo ifconfig eth0 192.168.1.100 netmask 255.255.255.0 

This change will be effective until the next reboot. 

  • Permanent Change:  

To make the IP address change permanent, you need to edit the network configuration file. For example, to change the IP address of the eth0 interface permanently, you can edit the /etc/network/interfaces file using a text editor such as nano or vim: 

sudo nano /etc/network/interfaces 

Find the line that defines the IP address for eth0 and modify it to your desired IP address. It should look something like this: 

iface eth0 inet static 

address 192.168.1.100 

netmask 255.255.255.0 

gateway 192.168.1.1 

Save the file and exit the text editor. 

4. Apply Changes:  

After changing the IP address, you need to apply the changes. You can either restart the network service or reboot the system: 

  • Restart Network Service: 

bashCopy code 

sudo service networking restart 

  • Reboot System: 

bashCopy code 

sudo reboot 

5. Verify Changes: After the system reboots, use the ifconfig command again to verify that the IP address has been changed successfully.

If you want to change your website’s IP address in your VPS with cPanel, you will first need to purchase an additional IP address.  

Once you have an additional IP address for your hosting, follow these steps to assign it to a specific website on your server: 

1. Login to WHM: Access your WHM (Web Host Manager) using your login credentials.

It may take up to an hour for the website to be fully mapped with the new dedicated IP. During this time, your website may experience some downtime or temporary issues. 

After the mapping process is complete, verify that your website is now accessible using the new dedicated IP address. 

That is all! Your website should now be successfully mapped to the newly dedicated IP address you have purchased.
