Configure Additional IP Address in Rocky Linux

 

Configure Additional IP Address

1. Check the NetworkManager connection

nmcli connection show
Output:
NAME                         UUID                                  TYPE      DEVICE
VMware customization ens160  2097545a-4a4f-4e7e-9c4c-bf4adc541236  ethernet  ens160

2. Add the additional IP address
This keeps the existing IP address and adds 192.168.1.254/24:
sudo nmcli connection modify "VMware customization ens160" +ipv4.addresses 192.168.1.254/24

3. Verify the configured IP addresses
nmcli connection show "VMware customization ens160" | grep ipv4.addresses

4. Apply the network configuration
sudo nmcli connection up "VMware customization ens160"
5. Configure DNS servers
sudo nmcli connection modify "VMware customization ens160" ipv4.dns "192.168.1.1 4.2.2.4 8.8.4.4"

6. Ignore DNS servers provided automatically by DHCP
sudo nmcli connection modify "VMware customization ens160" ipv4.ignore-auto-dns yes

7. Reload NetworkManager connection profiles
sudo nmcli connection reload

8. Verify DNS configuration
nmcli connection show "VMware customization ens160" | grep ipv4.dns
